Added the ability for the match to be finished if all bots left have
the same name. Should probably have some configuration and/or cmdline
options as well but that was beyond me.
Fixed a simple uninitialized ivar warning.
Use arrays as sets and all_but basically becomes Array#-.
Fix for odd errors I was getting. Heading#delta's to was sometimes not
a float. Dunno why. Couldn't properly track it back because of randomness.
Simple refactoring to make shell speed calculations reusable by bot
brains. Important for target prediction.
Added quit_when_finished configuration and made window close itself if
the game is finished. Important for automated tournaments.
