Game ending priority

[GoogleCodeExporter]

It looks like getResults (the check for game endings) has an issue with ending 
priorities.  It looks like it checks for repetition and 50 move rule draws 
before checkmate.  It doesn't happen very often but I was trying to use pyChess 
to generate some test cases and this caused some problems.

Utils/logic.py  around line 40.

I made the following modifications so I could get going on my project but I 
removed the LOSERSCHESS variant (Not familiar with it, sorry)

def getStatus (board):
    lboard = board.board
    board_clone = lboard.clone()
    hasMove = False
    for move in lmovegen.genAllMoves (board_clone):
        board_clone.applyMove(move)
        if board_clone.opIsChecked():
            board_clone.popMove()
            continue
        board_clone.popMove()
        hasMove = True
        break

    if not hasMove:
        if lboard.isChecked():
            if board.color == WHITE:
                status = BLACKWON
            else:
                status = WHITEWON
            return status, WON_MATE
        else:
            return DRAW, DRAW_STALEMATE

    if ldraw.repetitionCount (lboard) >= 3:
        return DRAW, DRAW_REPITITION

    if ldraw.testFifty (lboard):
        return DRAW, DRAW_50MOVES

    return RUNNING, UNKNOWN_REASON
