Minesweeper: Add "Custom game..." difficulty

Browse source 
This adds a dialog window which allows us to customize the size of the
board and the amount of mines that will be placed.
The current max amount of mines is 50% of the total number of cells
due to the fact that the generator algorithm takes too long to create a
board for higher percentages of mines.
