Minesweeper: Use a faster method to generate game field

The existing method was simply using a "randomly generate until it fits
our criteria" method to generate a game field. While this worked OK in
most cases, the run time was increasing seriously in boards whose
mine count / board size ratio was too big.

The new approach simply generates every possible mine location, shuffles
the array and picks its head. This uses more memory (shouldn't be a big
deal since minesweeper boards are generally miniscule) but runs much
quicker. The generation could still use some improvement (regarding
error handling), though :^)
