* [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.
* [Companion] Introduce new Boards class to further consolidate hardware metadata and remove some globals.
* [Companion] * RawSource::toString() and RawSwitch::toString() can now return custom hardware names (if given a GeneralSettings object) for the following types (respectively):
SOURCE_TYPE_STICK, SOURCE_TYPE_SWITCH, SWITCH_TYPE_SWITCH, & SWITCH_TYPE_MULTIPOS_POT;
* RawSource::isPot() and isSlider() can now return their own index position in potConfig[]/sliderConfig[];
* Switch indicator strings can be localized if necessary.
* [Companion] Refactor model printers to use new RawSource/RawSwitch capabilities; Simplify model-to-printer mapping scheme in multimodelprinter; Use const ModelData pointer.
* [Companion] Refactor how RawSource and RawSwitch selection combo boxes are populated, using cache-able data models instead of direct manipulation; Refactor some other Helpers function into their own namespace.
* Cosmetics & forgotten qualifier.
* [Companion] Speed up loading of model editor by only displaying Logical Switches and Custom Functions which are actually used.
* [Companion[ Constrain size of Repeat options combo box.
* Missing indent.
* [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).
