(svn r14750) -Fix [FS#1993]: in an MP game in SP mode no company would go bankrupt. Furthermore companies that passed the "bankrupt" period (4 quarters) wouldn't go bankrupt when loading the game back in MP. Now any company that is in MP or not "currently controlled by the player" in SP will bankrupt.
