Alien UI consistency update

Changes drop and throw to be normal buttons, standardized background colors (only one purple, no red) of every button. Hands are now prettier.

In this image I have toggled on jumping, throwing, have set my intent to tackle, are in hunt stance, and I'm also dragging a locker.

Let me know if you want to see anything changed.
