Subject: Perf improvements

 - The original '+=' of the GetHash method was taking ~10% of CPU usage for the game. This should improve performance considerably.

 - The next largest CPU usage we care about is the 'GetHash' method that gets called very often. Pulling the objects.GetHash() out will reduce hits on the method.
