[CS:CO] M4A1 for CSS v89 (v2 + no inspection)

+ Fixed file structure
+ Animations CS:CO

The list of changes is small (which is already small, it is practically non-existent), but nevertheless it is better than it was.

Removed the inspection animation, because it's unnecessary (because it's a cant).

Version: v89, not tested on v34.

P.S. I noticed a small joint with animations, but this is not critical.
