* [Companion] Refactor MdiChild & TreeModel, restore drag/drop, and more:
* Add full drag-and-drop functions to the models list, including model copy, move, and insert actions (also between windows);
* Add general radio settings copy/paste across file windows;
* Full MIME support with distinct types for various data (eg. models vs. general settings), also add new type for metadata (header);
* Copied/cut models can now be inserted in any spot (similar to drop-insert);
* Deleted/cut models can now be removed entirely (including the empty slot) for all radio types (any models after the removed one move up, like for Horus) (may need to make this an option);
* Empty model slots can now also be removed (any models after the removed slot move up) (but total # of slots is still maintained);
* Default model can be deleted (new default is picked);
* Completely revamp the actions system (copy/paste/edit/etc) to make it fully functional:
* Actions exist in the window, not just context menu, therefore all keyboard shortcuts actually work, w/out any duplicated code;
* Provides access from MainWindow in a comprehensive manner: all actions are available and properly updated based on selections in current editor window, w/out awkward event monitoring;
* More actions available from context menu, and somewhat reorganized;
* Also show all actions on mini toolbars right in the MDI window (possibly make optional later);
* Updated English localization file to account for plurals usage in new action item names (other languages need to be updated);
* Keyboard navigation in the model list now works/practical;
* MDI window uses all available height by default;
* Newly added models/categories are selected and highlighted; Category names are immediately editable; Model editor is/can be launched if wizard is not (need to make option);
* MainWindow updates:
* Edit toolbar and menu now showing all available edit actions, with proper context;
* File menu properly updates with all "general" radio actions: edit/copy/paste settings and simulate radio;
* Added Windows menu showing list of open windows (eg. to switch when full screen) and tabbed window option (need to make persistent setting);
* Immediate update of icon size preference;
* Do not delete toolbars when re-translating UI (they don't lose assigned position);
* [Companion] Restore model compare functionality by using new MIME data exchange system; Add ability to compare any number of models at a time; Multi-model printer now shows custom hardware settings for each dropped model (even from different radios).
* [Companion] Add missing monoblue & monowhite theme sdsync icons.
* [Companion] Model wizard starts with default model name populated.
* [Companion] Properly re-translate UI instead of recreating all the actions/etc.; Tell Mac specifically where to put our actions (seems to make it happier too).
* [Companion] Further improve handling of Window menu items/detection of sub-window changes.
* [Companion] Add file-close action.
* [Companion] Add user options and save preferences:
* Option to use wizard, open editor, or do nothing on new model creation;
* Option to remove empty model slots when deleting/moving models (in non-Horus radios);
* Options to hide toolbars in document windows (r-click on TBs);
* Save/restore size of document windows, and maximized/tabbed state;
* Save/restore size/position of model compare window;
* Add shortcuts for model compare, FW download, log viewer;
* [Companion] Disable being able to "delete" empty model slots (more awkward than helpful).
* Use drawText with tiem string like x12s. Change font ':' which where way to large for SMLSIZE
* MIDSIZE ':' lower dot was not horizontaly symetrical, moving it up one pixel
* Make it all ARM
* Let's try not to brake timer adjust
* Fix
* Create getUnit lua function
* Cosmetics
* Expend getFieldInfo instead of creating a new function
* Streamline units table
* @projeckk2glider comments
* Cosmetics
* Use simple division
* [Simulator] Create RadioKeyWidget class for UI buttons & refactor ButtonsWidget; Refactor SimulatedUIWidget (and subtypes) to use new RadioKeyWidgets/ButtonsWidget; Centralize help text for key mappings and get creative with some icons; Simplify some radio UI setups with rectangular buttons.
* [Simulator] Convert all simulator data I/O to signals/slots mechanism:
* SimulatorInterface/OpenTxSimulator:
- Now inherits from QObject to allow signal/slot interface;
- Allows data exchange on a per-item basis (eg. each I/O value is treated separately instead of sending whole arrays or structs of data);
- Checks for data changes and only emits signals when change is detected (GUI can now assume only new values are being sent);
- Manages its own 10ms timer (doesn't rely on GUI to do that);
- Sends "heartbeat" signals @ 1Hz for status monitoring;
* Simulator GUI:
- All data is exchanged between GUI elements as well as SimulatorInterface via signals/slots using standardized methods;
- Data is sent immediately, and only, when actually changed (eg. a control is moved) instead of in bulk at specific time intervals;
- Similarly, an asynchronous method is used for reading incoming data, w/out timers or loops;
- Improve VirtualJoystickWidget to be more encapsulated and configurable;
- Pause telemetry simulator if window is hidden;
* [Simulator] Move SimulatorInterface instance to separate thread, ensure safe asynchronous operations & proper timer interactions; Protect/remove some functions, & reorganize the order (cosmetics).
* [Simulator] Traces are now delivered to OpenTxSimulator and one or more QIODevice(s) can be added as recipient(s); Add SimulatorInterface::getCapability() for compile-time settings; Remove reversed POT1/SLIDER1 mixer exception (Taranis) requirement for SIMU; Fix plus/minus key delay on wheel event w/out encoder.
* [Simulator] Add current knob/slider/trim input value in tool-tips (KnobWidget and SliderWidget).
* [Simulator] Fix trims widget internal value not properly updating, and remove trim influence on virtual joystick X/Y value display (closes#4671).
* [SimulatorInterface] Add handling of transmitter input voltage, including a rough conversion of volts to ADC value for different boards, and default battery volts lookup function; Clear analogs array before starting.
* [Simulator] Add SimulatorInterface::init() method to separate pre-startup tasks; Report actual trim range, not just extended on/off; Change how radio widget states are restored; VirtualJoystickWidget: Connect trim changes directly from simulator, connect joystick events directly, report stick mode directly instead of setting values/constraints externally.
* [Simulator] Calculate default Tx V input based on configured range in radio settings (or warning V+2 for radios which don't support a range).
* [Simulator] Add functional aux. trims for Horus (closes#4699).
* [Companion] Remove problematic QMessageLogContext from AppDebugMessageHandler::messageOutput().
* [Simulator] Prevent trim change via slider if disabled for flight mode (closes#4600).
* [OpenTxSimulator] Fixes for Qt < 5.4.
* [OpenTxSimulator] Fix slot name.
* Fix possible confusion/data corruption when deleting radio profile (closes#4734, ref: #4686);
* Add Delete Profile action to Radio Profiles menu (closes#4736) (but remove from from app prefs. panel);
* Add confirmation prompt before deleting profile;
* Open profile settings dialog when creating/copying a profile (closes#4735);
* Make sure current (global) firmware flavor is properly updated when changing fw type/options in profile;
* Append "-Copy" to name of copied profile;
* Factor out Firmware global vars/functions in favor of static members.
* [Simulator] Remove extraneous format value in microsTimer; Better way to delete SimulatorStartupDialog (in case no event loop starts).
* [Simulator] No helpers dependency for SimulatorStartupDialog.
* [simpgmspace] Rename micros timer function and make externally available.
* [Companion] Fix possible uninitialized value in TreeModel (compiler warning).
* [multi_arm] Fix minor compiler warning (MSVC: "unsafe mix of type 'uint8_t' and type 'bool' in operation").
* [lua] Fix compiler warning ("'data' may be used uninitialized in this function").
* [OpenTxSimulator] Fix analogs array range.
* [Simulator] Auto-start simulator when SimulatorMainWindow is first shown (vs. before it was shown).
* [Simulator] DebugOutput: prevent possible mutex deadlock on buffer overflow (force queued connection for Qt < 5.3).
* [Companion] Display calibration data for Horus joysticks (MOUSE1/MOUSE2)
* Instead of copying current profile, start from a blank one
* Handle both add profile (which add a new (ie blank) one) and copy current profile which behaves like before (but says it)
* Avoid duplicate code
* [build] Add "all-libsimulators" target to build all simulator flavors at once.
* [build] Refine the "all simulators" target setup and deal with GNU 'make' parallelism issue (ninja=faster); rename to "all-simu-libs".
* [simpgmspace] Fix 2MHz and 16KHz timers on MSVC builds (fixes LCD/key/switch response delay on all AVR simulators); Introduce experimental use of Qt to simplify x-platform code (disabled by default).
* Qt timer scaling fix.
