Torsten Dreyer e9d24b05ca Introducing: The new navradio code (WIP) 
Here comes the work-in-progres code for a new navradio
implementation. Once completed, it will replace the
old/current navradio implementation.
The new code can be activated by setting
/instrumentation/use-new-navradio=true
at startup. This disables the old navradio implementation.

Current state:
- VOR works pretty good including the new
functionality 'code of confusion'.
- LOC and GS basically work
- backward compatibility (many properties) is to be implemented
