Death, taxes and refactoring: seriously revamped the low-level media code

to handle scrolling in a much cleaner and happier way. There's now a
VirtualMediaPanel which operates in virtual coordinates and can be made to
"view" any location in those virtual coordinates. By changing the view,
the view can be scrolled and the view can be made to center on a pathable
(generally a sprite) which will cause it to scroll around as the pathable
moves around in the virtual coordinate space.
