New console commands for AI debugging: gosolo and controlai

gosolo: make AI to take over every human player in game. Second command would give control back to CPlayerInterface.
controlai: give control of one or all AI players to CPlayerInterface. Command "controlai orange" turn orange to human player while "controlai" without color specified make all AIs human controlled players.
