* [Companion] I18N:
* Introduce new Translations class to centralize all related functionality;
* Add ability to search multiple locations for .qm translation binaries (local folders, resources, system paths);
* Add ability to reload translations dynamically w/out application restart;
* Improve support for loading Qt translations (if available);
* [build][i18n] Look for and include pre-built Qt translations with other translation resources; Generate translations.qrc dynamically with rest of build files; Add EN "translation" file (simpler UI string edits and possible abstractions); Rename ZH translation file to be country-specific.
* [build] Centralize finding all the Qt bits into root CMakeLists; Make sure QT_QMAKE_EXECUTABLE is defined; Disable dysfunctional simulator installer script generation.
* Cosmetics (unused includes).
* [Companion] Make language options menu dynamic based on available translations, and always show native language name; Allow changing language of some elements w/out restarting (esp. menus/toolbar buttons); Simplify menus/actions/handlers for themes and icon sizes.
* [build] Better way to generate translations.qrc using input file again (previous method was generating new qrc for each reconfig); Make sure common library is linked to other modules which may need it; Remove unused script.
* Refactor condition to avoid repeating the test in `else' and `endif';
* Suffix programs name with `${C9X_NAME_SUFFIX}' under FreeBSD, as for
Linux build, else cmake build is failing because a `companion'
directory already exist in the build directory.
* [Simulator] Create a reusable RadioTrimWidget; Move all trim-related enums to boards.h; Make sure aux trims are accounted for in SimulatorInterface; Trims now use toolbuttons with icons instead of pushbuttons with text.
* [Simulator] New buttons & icons for virtual joystick axis hold/fix toggles; Joystick ball is now slightly scaled to stick area.
* [Simulator] Virtual joystick now "follows" mouse clicks within the stick area (left-click on empty space will attract the control node).
* [build] Only build companion/simulator resources files once and include in common lib; Consolidate/cosmetics.
* [build] Fix "missing" translation resource files with some builds (since last commit); move resource file declarations to after app init as recommended; fix name of Qt translation file since v5.3 (this still only works on some systems with Qt installed and on the build machine).
* [simulatormainwindow] Move sub-window destructors to main destructor.
* [simulation] Move SimulatorInterface creation/ownership to SimulatorMainWindow.
* [simulation] Add option to unload simulator libraries after each use (eg. from Companion) so as to properly reset all statically initialized firmware variables; Introduce new SimulatorLoader class.
* [simulation] Hardening: Fix some potential crashes & 26 memory leaks, improve LCD performance.
* [simpgmspace] Init trims; Make sure `REa` is really defined (to match board files).
* [simpgmspace][opentxsimulator] Verify current running state before start/stop; Move rotary enc. init.
* [simpgmspace][LcdWidget] Improve performance by moving LCD content change check to lcdRefresh() & limiting LcdWidget refresh time to 60 fps max.
* [simueeprom] Ensure thread could be started, set default running state to false.
* [simufatfs] Fix paths report trace.
* [eepromimportexport] Fix memory leaks resulting from import debugging scheme being used.
* [customdebug] Introduce new scheme for custom debug output in compliance with Qt recommendations (see docs for QLoggingCategory).
* [opentxeeprom] Fix extra conversion table cache elements being created and also not properly deleted (and hence leaking).
* [opentxinterface] Unregister EEpromInterfaces in unregisterOpenTxFirmwares();
* [storage] Unregister storage factories on exit (fixes leak); create virtual StorageFormat/StorageFactory destructors (prevents warnings).
* [helpers] GVarGroup now emits own signal, no need to pass ModelPanel pointer (removes dependency on modeledit.h)
* [DebugOutput] Clear simulator trace hook before exiting (prevent possible issues); Fix leak and possible bad QString allocations when reading from buffer; Fix leak with combo box event filter.
* [TelemetrySimulator] Fix leak by deleting LogPlaybackController object on exit; Only set up data fields once; convert timers to static.
* [build] Consolidate all Companion/Simulator shared items in `common` library to reduce build time/etc (node & edge still remain awkward).
* [simulatorwidget] Delete removed spacer object (previously-forgotten "26th" leak).
* [DebugOutput] Fix stray trailing characters issue with new text buffer allocation (from previous commit); Increase maximum buffer sizes to better accommodate slower systems.
* Cosmetics.
* Scripts
* No suffix for docker image
* generate sdcard file to subdirectories to match companion changes
* Massively increase options for simus
backup lua_fields info for lua docs
* Allow both nightly and release to be built
* $ ambiguity
* Cleanup
* Tidy up
* Cosmetics
* [Simulator] Increase resolution of CoGetOSTime() on Windows MSVC (possible fix for #4529, ref. #4342).
* Return total time, not delta time.
* Improve efficiency.
