* [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.
* Refactor CompStoreObj to use templates. Clean up some formatting.
* [Simulator] Add SimulatorOptions type to replace individual simulator options; Fix storage handler for custom types; Cleanup some redundant code.
* [Simulator][Joystick] Rework the joystick options/calibration dialog. Can now enable/disable/select the Joystick from there. Delay start of calibration until Start is pressed (otherwise looks like last calibration didn't work). And generally refactor a lot of it to be smarter.
* Cosmetics.
* [Simulator] Add state handling for RadioWidget class. Split code to cpp file.
* [Simulator] Add SimulatorStartupDialog as its own UI class.
* [Simulator] Multiple changes and new features:
All Horus data source options are now fully supported with data properly saved after use (SD path, .otx file, or custom data path);
Loading .otx files now works for all radio types (but not saving data back to .otx);
Switch and knob/slider states are now saved to per radio profile;
Joystick configuration/calibration is now available directly from inside Simulator;
Due to refactoring, all previously saved per-profile simulator settings are now invalid;
Further consolidated simulator dialog startup/shutdown, now handles temp. paths internally, etc;
With WIN_USE_CONSOLE defined, Simulator and Companion when started from Windows command line will now use that console for all messages (instead of opening a new one). This allows full debug output to be seen at all stages of execution and after exit.
* [Simulator] Fix build w/out SDL Joystick support.
* [Simulator] Fix bogus throttle warning on simulator start; Add forgotten RadioWidgetState flags to stream handlers; Add debug state saver in SimulatorOptions.
