GamestateVisualizer: Visualize MiteCom communication

The GameStateVisualizer currently only listens to the SPL communication protocol. Would be really awesome if it would listen to MiteCom as well. Only an awesome feature, not necessary for functionality.

What is the state of the TCM/GSV anyways? In past competitions I have seen the main interface of the GameController on a second, audience-facing screen, instead of the GSV.

Also, I think the first step would be to set a definite standard for team communication (I've heard there are two competing standards), or (as in the SPL) make the basic info (pose on the field + where the ball is seen) part of RoboCupGameControlReturnData.
