Snake: Use a statusbar to display the current and high score

The food bitmaps would sometimes be placed underneath the score text,
which was a bit hard to see. Use a statusbar like we do in other games
like Solitaire.

Note the default height change of the Snake window is to make the inner
game widget fit exactly 20x20 cells.
