Don't segfault on premature solve moves in Mines
If a save file contained a solve move as the first move, Mines would
dereference a null pointer trying to look up the (at that point
undetermined) mine locations. Now execute_move() politely returns
NULL instead.
This save file demonstrates the problem:
