futher tweaks

1. made ammo found on corpse with greater chance
2. made controllers more fragile
3. tweaked actor base stamina depletion rate for all classes
4. removed long-sterm stamina penalty for some buffing items and added a
greater, one-time nutrition penalty instead
5. added custom actor_effects_data for all actor classes:

- classes now differ in ammount of health on which they attain 'limping'
state - its much lower for assaultrt
- classes now differ in how poned they are to dsiplaying camera 'hit'
animation - distracting player after getting hit (assaulter is much more
resiliant to this on the contrary to recon)
- classes now differ how soon 'heavy breathing' from stamin drop kicks
in - its significantly delayed for recon

6. made NPCs react to danger for longer periods of time
7. completely overhauled vision settings for all NPC ranks in attempt to
finally make them proper for all lighting conditions
