Fixed bug from debug mode (lol)

More about this bug here: http://www.battlecode.org/contestants/forum/1/87/

It caused NullPointerException, because allRobots list was null (includeBytecodesUsedSignal argument had "false" value when called by user interaction in debug mode), and there was missing null check on line 557.
Just code formatting

I couldn't stand how my previous commit looked like.
