Subject: [PATCH] Check if game is over when parsing fen to position

It can solve the problem that after tapping Move Now after this kind of FEN import,
AI can't do 2 move in a row. (when specific settings are turned on)
**@@@@**/**@OO@**/**@OO@** w m s 4 0 8 0 1 0 0 1
**@@@@**/**@OO@**/**@OO@** w m s 4 0 8 0 0 0 0 1

But it still can't be solved for the following FEN.
**@@@@**/**@OO@**/**@OO@** w m r 4 0 8 0 1 0 0 1
