add: mouse idle anim

[ROdenFL]

What Does This PR Do

Add 9 idle anims for mouse. For of them can be used by ai mice, some only for sentient one.

Mouses are immobolized, during the animation.

There is 20 seconds cd between animations.

Current lists for now:

Ai mouse and not sentient player: shake itself, washing up, sniffing, scratching.

Sentient player: no sentience + ass shake + dance + cig

Why It's Good For The Game

Animations are made cool. It can be quite funny to them in-game.
