Make auto-aim work with red goal

Problem to solve: When the game is played in non-remote mode (full 12x12', dual-goal field), we need to be able to detect the red goals, but we're currently only able to detect the blue goal.

Almost done. I finished multi-cam support but this falls into the 'I can't train it because I don't have a robot' valley.
