Visual feedback for collision

[Dr-Horv]

If you bots try to enter the same space there is a collision, see the following scenario:
|A| |B|
Now both A and B tries to enter the empty space between them, since they cannot both occupy the same space the logic is that there is a collision and they end up in this state:
|A| |B|
A is stunned.
B is stunned.
State also has information that there was a collision in the position for the empty space, this is not rendered though. which makes it confusing for observers. This should be remedied.
