Minor cleanup changes.
Improved recalculateCellSize to handle rectangular boards.
Added in a horrible background, as well as redoing the UI to switch between vertical and horizontal modes depending on the screen size.
Also removed the stupid coloured rectangle and added in a glow bar to signal whose turn it is.
Changed background colours to be *slightly* less horrible, and also fixed an animation issue.
