Title: 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.
