* [Simulator] Debug output: Adjust exclusion filter, help text <kbd> background color, fix help text typos & mark as translatable.
* [Simulator] Radio Outputs: Fix wrong FM highlighted (closes#4408) and current FM not highlighted until switched once; Change highlight color role of active LS/FM so it is always shown (fixes#4393); Active LSs now much more obvious (bold font & sunken frame).
* [Simulator] Rework some SimulatorMainWindow functionality:
* Fix floating dock widgets appearing behind other applications on Linux (https://github.com/opentx/opentx/issues/4403#issuecomment-277510273);
* Fix previously-unused floating dock widgets appearing in top-left corner upon subsequent launches of application (https://github.com/opentx/opentx/pull/4385#issuecomment-277315158);
* Fix various anomalies due to not using a "central widget" in QMainWindow (extra separators appearing, vertical resize not working in some cases), radio widget is now central by default;
* Add (keep) option to float the radio widget separate from main window, though this may cause the minor visual anomalies mentioned above;
* Add options to disable radio widget size constraints while docked.
* [package] Add QtSvg support DLLs for Windows.
* [Simulator] Add images/css resources for new version; Create SimulatorIcon and SimulatorStyle classes; Build with SVG support, remove unused bitmaps.
* [Simulator] Improve and simplify VirtualJoystickWidget resize event (sticks maintain X/Y position) & improve values layout w/out trims.
* [Simulator] Refactor Trainer simulator to use VirtualJoystickWidget, gains lock/hold buttons and X/Y position readout.
* [Simulator] More compact layout for Telemetry simulator, reduces min. width and adds scrolling columns to allow smaller window sizes.
* [Simulator] Add new SimulatorMainWindow and RadioOutputsWidget UI classes.
* [storage] Add non-persistent sessionId() to AppData for tracking currently active radio profile ID.
* [Simulator] Major UI updates:
* Use a MainWindow interface with dockable/floatable windows, proper toolbar & menu;
* Persistent size/layout state of all windows/docks/etc between uses, per radio profile;
* Completely separate radio Outputs window with configurable layout (also persistent between uses);
* Translations now enabled in standalone Simulator, follows main Companion setting (they need a lot of updates);
* New custom icons throughout, toolbar icon sizes adhere to user preference in Companion.
* [Simulator] Debug Output console updates:
* New filter feature with optional full RegEx support, can work in inclusive or exclusive modes (full help text is included in UI);
* Up to 50 user-defined filters are saved to permanent settings, also a few predefined filters are provided;
* Saves/restores the last filter used and if it was en/disabled;
* Added word wrap and clear screen features;
* Configurable scroll-back buffer size;
* Increased efficiency & performance of the buffering/printing process.
* [Simulator][OSX] Visual UI tweaks for OS X.
* [Simulator] Fix some debug console settings not being restored properly.
* [Simulator] Add ability to hide/show menu bar; Persist view state of menu bar and radio title bar; Reduce font size on OS X; Other small visual tweaks and improvements.
* [build] Add QtSvg to Linux build scripts (a guess for Dockerfile).
* [build] Fix for Qt 5.3.
* Add OpenTx headers to new files.
* [Companion][storage] Update GeneralSettings() initializer to use current sessionId for profile data retrieval, removes workaround for standalone Simulator being started with arbitrary profile; AppData: always update sessionId when global id() changes.
* [X10] Fixes for new simulator
