(carrier_planes): New parameter msl.

Browse source 
(carriersatxy, pln_onewaymission): Pass zero.  No functional change.
(pln_airbase_ok): Pass whether the plane is a missile.  This fixes
non-x-light missiles on ships without capability M_FLY.  Broken in
rev. 1.76.  Launch and interdict weren't affected.  Air defense was,
but the stock game has only x-light SAMs.
