I've imported some of the "character" images from ArduLO, converted to
GIFs because they're easier to work with. They've been imported into a
new Bitmaps structure so they only need to be loaded once at app start.
I've also cleaned up some of the drawing code, and created a series of
helpers for dividing Rects into a 3x3 grid, to make it easier to define
the layout. I've also stubbed out "theme-support". :)
