Unchecking all IOS patches now also unchecks main IOS patch checkbox Increased size of header, in hope that the date won't be cut off... Changed TODO list stuff VERIFIED UNDER: Windows TO VERIFY: Linux (not sure if outputting WADs correctly, should be checked) Mac OS X (not such a priority, as mono can be quite hard to set up on OS X)
