4.12.2 de-bugging

[SPAD-1949]

Got it running.
Tried along with start from the box, learned a lot.
But sometimes your mates just start at any point in an unpleasant direction.
Ground object avoidance is a delicate balance.
If you take just predef 20 mtrs of distance, it seems your mates are not following.
Better reduce standard distance to 9mtrs.

Flight model and shooting skill changes are strong as far as I can see.
I need to level down the difficulties in my missions.
