* [Companion] Radio -> General Settings -> Hardware: Hide external serial port option for Horus; Fix battery voltage and current calibration changes not registering (wrong signal handler name); Prevent modified() event if edited value wasn't actually changed (this is a problem in all panels with onEditingFinished() signals); Fix some cosmetic layout issues when no hardware names are editable.
* [HardwarePanel] Minor layout fix for BT option.
* [HardwarePanel] Fix comparison issue.
* [Companion] Move RadioData constructor.
* [Companion] Move getCapability(SwitchPositions) to Boards class.
* [Companion] Show custom channel, g-var, & curve names throughout UI; Remove redundant name formatting and other unused functions in ModelPrinter and Helpers; Add CustomFunctionData::isEmpty().
* [Companion] Add LogicalSwitchData::isEmpty().
* [Companion] Fix small bug in HardwarePanel.
* [Companion] Rename logical switches to "LSw##" in selections lists to avoid confusion with "L#" and "LS" hardware controls; remove unused RotaryEncoderString().
* [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)
* [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.
