Stubbed lookahead ai
Removed AI*.js files. AI is a single metaobject that is instantiated with a reference to behaviors that can be mixed in.
Fixed bug where behaviors were being added to AI prototype, so all AI instances were the same over time. Behaviors are now added to the instance before it is returned.
EOM, app unstable. Refactoring Board and entire game to handle indexes rather than points. Is this wise?
