* renamed from rendered to remote aircraft as discussed
* adjust samples
* removed no longer required functions in timestampobjectlist
* changed connectioStatusChanged from uint -> int
* common base class BlackCore::CSimulatorCommon
* using providers IOwnAircraftProvider, IRenderedAircraftProvider
* using revers lookup in mapping
* using CSimulatedAircraft / CSimulatedAircraftList
* return values (success/failed) for member functions (e.g. setTimeSynchronization)
* getMaxRenderedAircraft / setMaxRenderedAircraft prepared
* common base class for FS drivers
