Set up screenshake button ui

Rewrite Goofball's doScreenshake() function to be much more modular and multi-purpose (also rename to do_screenshake() to match other functions)
Add networking needed to make screenshake work. Works with AOV version of tsuserver3 (button screenshake only so far).
Add get_theme_pos helper function, currently unused.
