* [Companion] Qualify all remaining QObject translations with proper class/object names; Centralize some common strings into constants.h.
* [Companion] Replace all instances of some common strings with macros from constants.h.
* [Companion] Fix translation warnings from lupdate.
* [Companion] Add Qt tr() functions to all radio data classes instead of using generic QObject type. (no functional changes)
* Small fix for gcc.
* Move more element name string generation to individual classes; settle on nameToString as function name.
* Also put firmware build options translations into Firmware scope.
* Added: scripts for nightly build (SD card content, Russian voice), system sounds: done, other sounds: partially
Fixed: gTTS issue with unicode (Cyrillic) chars in command params (gTTS module instead of system command)
* Fixed: gTTS issue with Unicode (Cyrillic) chars in command params (gTTS module instead of system command), for release candidates and release
Changed: SOX params to normalize the audio
Added: "psv" parameter to export list of audio files into PSV format (see TTSAutomate https://github.com/CaffeineAU/TTSAutomate , to generate voice files using TTS engines from Microsoft, Amazon, Google etc)
Added: some extra voice files for RU
* [Companion] Refactor radio data classes to own files, out of eeprominterface.cpp. No functional changes.
* Move files related to refactoring. No functional or code changes.
* Fix clang warning and an include path.
* Fix indents on curvereference.cpp. [ci skip]
* [Companion] RawSourceRange: Fix for timers and RTC; Remove unused "single precision" flag and logic; Add logic for "short" timer handling.
* [Companion] Add TimerEdit class for editing negative times; Implement TimerEdit in LS, CF, and Telemetry (bars) editors;
* [Companion] Refactor LogicalSwitchesPanel for fewer & more efficient updates; Fix newly-added LS not being available in source lists; Fix bug with timer/rtc comparison values getting reset to value of spin box instead of time editor.
* Add forgotten #include.
* [Companion] LogicalSwitchesPanel: Update raw sources list upon screen refresh (fixes#5374); Improve data entry in spin boxes (fixes#5375).
* Make gcc happy.
* [Companion] Set proper RawSourceRange for GVars, trims, mixer scripts, and sticks/switches/cyclic/MAX.
* [Companion] Fix backwards precision/range logic on telemetry sensors offset spinbox; Fix other minor range issues with ratio & offset.
* [Companion] Remove short limit on min/max timer values for LS & telem. bars.
* Switch to TimerEdit in maxLibQt.
* Fix gcc build.
* Remove unused files.
* Caps fix.
* [firmware][ARM] Adjust some value limits for mix sources and update editing UI for LSs, CFs, & telem. bars:
* Increase timer limits to +/-8:59:59 when used with LSs, CFs, & bars;
* Increase Lua script output limits to +/-30K;
* Trim limits based on extended limit model setting;
* Limit TX voltage to 25.5;
* Limit TX time comparison value to 29:59m;
* Use proper GVar limits (user-configured), display precision, & unit in LSs & telem. bars;
* Display timer values properly with hours (instead of mmm:ss).
* [firmware] getTimerString() would fail with times >= 100min if hours weren't shown.
* Fix builds w/out GVars.
