Automaton artist colors are now passed in in the same object as the rest of the settings.
Slight optimization: don't draw grids with no thickness or color.
Add the debug-to-console function to Grid.prototype.
Add a few sets of cellular automaton rules.
Add automaton "presets" to group rules, seeds, and random artist settings.
Some slight cleanup for the automaton setup.

It doesn't seem much cleaner. :-(
Some size and positioning fixes for the automaton canvas.
