winemine: Set mines after first choice.

The first choice never is on a mine in Windows. This can be tested by making a custom game with as many mines as possible, and then playing the start of many games, and the first choice will never be on a mine. This is done to make the game reasonable, since after the first choice there will at least be some information given to make the next choice.

winemine: Set mines after first choice.
