EstimateStabDamage: updated code.

Browse Source 
Black AI: 
- reduce stab attack attractiveness if target is not very close
- reduce stab attack attractiveness if soldier sees more than one opponent
- for HTH attacks, skills don't have effect on choosing attack type for boxers
- reduce HTH attack attractiveness if soldier sees more than one opponent
- allow to increase autofire bullets by reducing aim in NCTH if LIMIT_MAX_DEVIATION option is enabled
