Some items had completely wrong permissions - this is easier than correcting them all.
The ability to set permissions in xml is retained since there are use cases for this (e.g. to create no-mod library scripts)
Library items always need the same permissions, so it doesn't make sense to load them from the xml files. This just opens the door to permissions mistakes.
This will cause visual params to be persisted along with worn items. With
this, alpha and tattoo laters will be saved. Multiple layers MAY work, but
not tested because I don't use Viewer 2.
