Removed --bigscreen from iso module.cfg.
The arg is a bit of an abomination, and should really be removed from the code. iirc, it was a 'dirty, dirty hack' I put in while waiting for Sirp do to it right. Either he or Krista^ has now, I think.
Added a projection-test module which relies on iso.
This way, I won't annoy everyone by making changes to iso. :)
