Subject: do-not-create-too-many-mines
freesweep enters an infinite loop when placing mines if the user's
configuration has it creating more than (boardsize - 9) mines. This is
caused by game.c:510 not allowing mines to be created within a 3x3 block
at the centre of the field, while the initial configuration allows for
more than (boardsize - 9) mines to be created. This patch makes a board
size of 3x3 invalid because no mines can be placed and lowers the
maximum allowable number of mines on a board to (boardsize - 9).
Patch provided by Seneca for freesweep-0.88
