4.11 - AI debugging

[Uzin]

Successfully installed 4.11 over vanilla 4.101.
Anyway, a lot of work was done. Thanks to DT.
Tried some QMB and single missions.
Some obsevations:
- former *.trk files not accepted by the new version.
- longer than 10 minutes *.trk files recored differ essentially from that what was observed in the flight.
- CTD at Quick mission without any known reason.
- the possibilities of waypoints - take offs aside (=pair) - do not work in QMB , weird places occupied by AI planes.
Surely these and other bugs will be repaired by DT, I hope.
Ik-3 has roundels on one wing upper surface only, second wing lower surface only. Is it correct ?
