* signatures in contexts
* some specialized functions in aircraft list
* context menus in aircraft view
* default "blinking" implementation in driver common base class
* GUI component for aircraft parts
* remote aircraft selector component
* Adjusted GUI for internals component
* Enable / disable debug messages from GUI
* Allow to init engines directly
* Removed unused async sort in sequence
In same step fixed found issues in interpolator
* allow to set max rendered aircraft
* 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
* support of property index
* used support classes BlackMisc::ITimestampBased, ITimestampObjectList and ICallsignObjectList
* fixed some issues in related aircraft situation class in same step
