[Bug] Fix attack animation + add eat animation

[mbc]

I fixed the problems on my attack_twitch branch that were detailed in this thread.

Sleepy pens and the silenced .22 won't trigger the attack animation anymore, and neither will using items on yourself. 
People seemed to like it for eating/drinking stuff though, so I added a little eat animation that squishes your character slightly when they take a bite/sip.

Hey, a quick note. The traitor geneticist screwdriver also plays the animation even though it's supposed to be completely stealthy.

Fixed it, thanks for pointing it out!
