Minesweeper: Perform sanity check on configuration (#1300)

Browse Source 
This addresses the issue found in #1261. Previously we weren't doing
any form of sanity checking on the values in the configuration file,
meaning that a user could input a ridiculous number of mines such that
the number of mines is larger than the number of squares on the field.
