Subject: For EXT-1121: Attaching / detaching objects doesn't affect the
 Current Outfit folder and EXT-1090: Attachments detach on login.

This is still in short term fix territory - trying to avoid creating duplicate attachment links when wearing outfits.  It's not 100% robust because of the possibility of race conditions.
