* [simulator] Keyboard and mouse control adjustments:
~ Make kay/mouse navigation more consistent between radios and ensure keyboard events are always properly detected (eg. after clicking on a control);
* Fix mouse wheel direction for rotary encoder emulation (fixes https://github.com/opentx/opentx/issues/4160);
* Fix page up/down buttons on Horus (also #4160);
~ Horus rotary encoder can now be controlled with +/- keys (also keeps X/C, otherwise supersedes https://github.com/opentx/opentx/pull/4087 );
~ DEL key now another alternative for ESC/BKSP (brings all controls to number pad);
~ "=" key now acts same as "+" key (+ requires SHIFT in main row on most US keyboards);
* Fix controls direction when using mouse wheel over RC switches;
+ Add help text showing keyboard mappings for each radio type (activate on F1 key).
* [simulator] Enable mouse wheel scrolling on radios w/out a rotary encoder (acts as +/- keys on X9D, PU/DN keys on 9X).
* [build][OSX] Fix clang warnings.
* [build][OSX] A few more warnings taken care of.
* [build] Fixed yet more build warnings across all platforms.
* [build] Fix final warning due to bad CMake flag.
* [build] Remove unused variables as requested, fix indent.
* Fix output display limit type for 8-bit targets.
* [simulator] Save and restore Simulator window sizes and positions (based on current radio profile).
* [simulator] Set startup throttle stick lock in standalone sim based on default mode in current Companion radio profile;
Add new flag indicating standalone simulator;
Unique titles for simulator console windows.
* [simulator] New/updated Simulator startup options:
Radio profile used for standalone Simulator can now be separate from Companion;
Allow selecting a radio profile and EEPROM image file (in addition to radio type) at startup via GUI and CLI;
All startup settings are saved between uses.
* [Windows][MinGW] Update some WIN32 macro checks in source code to be MSVC-specific (not needed for GCC-based builds).
* [build] CMakeLists updates:
Adjust for Windows MinGW builds: now fully compatible with Qt5.5+ and MinGW-w64 toolchain (included in Qt installs);
Add option to specify path to required libraries/includes (instead of hard-coding `c:\programs`);
Add package check for Python and use found executable name;
Remove custom FindSdl package handler in favor of stock (and improved) CMake one (still works with Windows);
Do not force SIMU_AUDIO and LUA_COMPILER in SIMU builds (leave it up to user);
Add SIMU_LUA_COMPILER option specifically for SIMU builds (default = ON);
* [build][Windows] Rewrite/Fix Windows Companion `install` target, with two options:
a) just copy supporting Qt and c++ DLLs to build folder so programs can be quickly be run from there (this is default and similar to the old behavior);
b) full installation to CMAKE_INSTALL_PREFIX path, including all binaries, supporting DLLs, language files, and OTx utilities.
Option b) can be selected with new WIN_DO_FULL_INSTALL parameter;
Also cleans up the Linux install a bit and consolidates the OS X parts;
* [simulator][Windows] Add option to build Windows simulator with system console/terminal enabled (both standalone and when launched from Companion). Mostly useful for debug as it gives output messages much sooner in the startup process than the current debug console. Also helpful because you don't have to open it manually on every launch, and it remembers last window position and size. Possible candidate for a user-selectable runtime option in the future.
* [Windows] Fix MSVC build issues.
* [build] More build fixes:
Use a customized FindSDL.cmake script again due to bugs and deficiencies in the official version (based on script from CMake v3.7);
Fixes missing SDL DLL error in NSIS installer);
Use string for Timers option (checkbox in GUI is confusing);
Remove an unused variable.
* [simu][Windows] Fix f_getcwd() cutting off too many characters (fixes SD browser interactions).
* Add FY805 protocol
* Fix stray space
* Fix multi sending 120% instead of 100%.
* Implement a custom telemetry for the multi module
The custom telemetry allows the module to tell the telemetry protocol to OpenTX and also allows signaling the status of the Module (e.g. invalid protocol) to OpenTX
This should also close#3979.
* Cosmetics and a few small bugfixes
* remove empty if
* Move status line directly below the mode to be always visible when selecting a protocol
* warn if internal RF module is on
* Replace sprint with small helper function to build on AVR ARM (AR9X, 9XPRO, …)
* TR in wrong order, RF_PROTO_OFF inverted
* Refactor definition of Multimodule protocols to have one central place to define all multi protocol properties
* Also update protocols in companion
* Update multi version number to display as a.b.c.d
* [simu] Reduce width of all simulator windows and also height of Horus window. (https://github.com/opentx/opentx/issues/3135)
* [simu] New vertical channel outputs layout for all simulators, all outputs in one window and horizontally scrollable. Consolidate outputs and gvars widgets to one code base for all sims. Make simulator dialog re-sizable.
* [simu] Make simulation dialog resizable, and greatly reduce minimum size requirements of all simulators. Introduces new VirtualJoystickWidget class with all controls. Simplifies every simulator dialog UI form.
* Fix for issue with trackpad & mouse wheel: Small movements up or down send delta=0, causing always events in the same direction.
* Changed keys to X,C
* [Companion] MdiChild now use a QTreeWidget instead of a QListWidget (for Horus compatibility)
* [Companion] Horus models.txt parsing / writing implemented
* Fix for QT53 (#4109)
