Updated Dima bot damage settings, added ShakeCamera() to recoil.

Added Dima's destructible bot support.

Scrapped nearwall system cause I didn't like it

Added optional verlet correction, adjusted recoil animations.

Reworked recoil system, changed scope mechanic to take advantage of SetCameraFoV, split model into shapes to improve near-wall behaviour, added left-hand mode.

I used too much spread increase per shot in the first version so I reduced it
