* changed aircraft view to siumlated aircraft models / views
* functionality to change fast pos. updates (signals, slots)
* allow to request text message widget from aircraft component
* extended unit tests for interpolator / parts testing
* allow to skip sorting when splitting by time
* update ot aircraft to FSX in own member function
* Skip time sync parts (FSX) when disabled
* using split by callsign everywhere
* helper function to insert_front
* revised linear interpolator
* renamed to remoteAircraft
* renamed to container() in providers (gettters are usually copies)
Issues why changes did so long:
* insert in list is not adding in front, but same as push_back (that was confusing)
* naming of values before/after in interpolator was ambigious
* QMap keeps values sorted by key, not arbitrarily
