FindNearestUngassedLand, FindNearbyDarkerSpot:

- optimization: don't check spots already checked in previous loop
- increase max distance to 35, reduce to 25 if complex AI not allowed, reduce to 15 in realtime
CanDragPerson: use world movement cost instead of LOS check.
Say TAUNT_RELOAD, TAUNT_OUT_OF_AMMO taunts if mag size > 4 or Chance (CHANCE_SAY_ANNOYING_PHRASE).
SpotDangerLevel: also check Water and CorpseWarning for danger level = 1.
ManSeesMan: only call SetNewSituation if location or level are different to reduce frequency of AI re-evaluation.
Only allow radio animation on initial red alert, if sector is not jammed.
Press ESC to stop dragging.
