Turned board is probably not parsed correctly

[croeer]

If black is to move the rotated board is probably not correctly recognized.

Solution: rotate the board if player black is detected (needs #5 )

Danger with this idea: player can rotate the board by himself. If he does so, the parsing will be wrong again..

Convention: the board is viewed from each players perspective, i.e. leftmost downward field is a1 if white is to play, and h8 for black.

Autorotation can be turned off via command line parameter
