Adds Hunting Rounds

Adds a system for projectiles to inflict additional damage on specific kinds of simple animals.
Adds special bullets for certain rifles which are very effective against 'animal' SAs such as giant spiders, bears, carp, and such. The bullets do less damage to other targets such as humanoids.
Replaces the southern cross gun locker regular ammo with hunting ammo.
