Delete Robot Roller-Derby Disco Dodgeball

Both of these pages refer to the same game:

http://www.giantbomb.com/disco-dodgeball/3030-44975/

http://www.giantbomb.com/robot-roller-derby-disco-dodgeball/3030-44570/

I would recommend deleting this one, as it is entirely written by the developer of the game...

@beachthunder: I'm not sure why it being written by the developer matters as it seems the information is valid and there is nothing talking about how good it is or anything. The only problem I can see is maybe the links of where to buy the game? But if that is the case then that can probably just be edited out.

Done.

Kept the longer one as it was more complete. Being written by a developer is fine, as long as it stays within our usual wiki rules.
