1. Thanks to Greg Hendershott the color scheme now matches the original.

2. I've added some caching to take the strain off the GC: tile images are
only made once, and when nothing's happening the image of the grid isn't
being regenerated.

*Neil*: Does the update fix the choppy animation on your box?

*Matthias*: Would it make sense to have an option on (big-bang) for it not
to redraw if the world hasn't changed?
