Christmas update:

* New, unique shove animation
* No more animated shell ejection, now uses particle-based shell ejection
* Slightly reduced idle animation intensity

New feature: Random zip tie colors. This feature is disabled by default, and can be enabled with the convar "cl_buy_favorite_nowarn". See the shared content's patch notes for more details.

Fixed a long-standing issue of crashing in single player when switching away from this weapon. Thank you, Lt Rocky, for all of the help with solving this issue.

Improved the position of the world model to better line up with the survivors' hands

Fixed the right hand IK during the reload so that the hand no longer floats

Fixed the reloading bug. This fix does introduce an unavoidable but very minor visual glitch where the magazine may disappear for no more than a single frame.
Improved the left arm to better support 90 FOV.
