Fixes for handling human-entered Flip games. The clicked-on square

Browse Source 
always got a flip animation even when it wasn't one of the ones
being turned, and a square with no effect at all was still counting
as a move.

Since it's an invariant of Flip's internal generator that every
square includes itself as an effect, this never comes up in auto-
generated games.
