Square black buttons animation should push in then out #212

When you push a button, it should go inward, then spring down to its rest position. Likewise when you push a button "off".

Button sounds in FMOD will respond to this animation to have the correct push in/out sounds (once I have a good audio sample of the button). The dataref number should be consistent and a clean even number so it translates well for FMOD.

The laminar A330 is a good example of this. Watch how the button animation moves, and how the dataref is clean and allows for the sound to be accurate:
