Space > Indent in roomauth; add targetUser for hex

/roomauth previously had spaces instead of tabs except in 3 lines (however alignment of code was correct) and /hex would be better with targetUser. Inspite of all that, I don't really know how !targetUser (and targetUser) will react to how I placed them, so it'd be nice if you would confirm that and PM me on Frost regarding the matter. If there are no problems, you can merge this (obviously).
