隐藏的收起武器（1.2.x）

I received a request to make this mod on another mod, so here you go =)
I made this one relatively quickly, so there might be something missing—if so, please let me know.
Note:

• If you draw a weapon, they will appear out of thin air (obviously).
• Due to the animation being linked to the holster, all weapons are now drawn from the back by default (seems to be a preset state). This looks particularly weird for bows.
