Organising flights in a multisquad campaign.

[FG28_Kodiak]

Select a callsign for a group and take a look in the mis file after saving:
Example:

[BoB_LW_StG2_II.03]
  ..
  ..  
  CallSign 27
  ..
  ..

this would be CallSign27 in code.

- Found an other 'Bug' - if there are no Enemy planes available in mission, i forgot to create a "no enemy in range" message - fixed.
