Added task :test that only runs ch* files, not games like ufo or snake.
Fixed latest to actually run latest by mtime.
First pass at snake. I'm not happy with this. They do a lot of stupid things.
rearranged / organized and deleted dead code
First level cleanup. Got rid of conds in favor of case. Used better /
cleaner code. Generate snake-head/tail/body.
Switched to use 'u 'd 'l 'r instead of strings
Cleans up comparisons a lot.
Swiched everything over to assoc where possible
