* added new utility funtion is model list / aircraft list
* added setters/getters for CSimConnectObject
* added setters/getters for InterpolationStatus / PartsStatus
* added CSimConnectObjects (better encapsulation)
The produced QByteArray was missing the null terminating character,
since QByteArray::append() only added up to and not including '\0'.
This was also the reason why sometimes planes did not change their
aircraft models properly.
Pitch and bank angle in CAircraftSituation are according to the
common aeronautical convention:
* Bank in degrees, positive = roll right
* Pitch in degrees, positive = pitch up
Microsoft Flight Simulator is using inverted angles, which was incorrectly
adjusted in the interpolator. This caused wrong values for X-Plane.
This angle correction is now moved into the MSFS specific plugins.
Additionally, so far the pitch and bank angles from own aircraft were
not yet corrected for MSFS. So we did send wrong values to the network.
