To get this to work, I had to disable the dupe link check I put in a couple of commits ago.
When the viewer adds wearables to an existing outfit, it first requests deletes of all the existing links before creating a new set.
Since these messages are async, the creates were being received before the deletes had a chance to complete, resulting in missing current outfit links.
However, the dupe check shouldn't be as important now that broken links have been fixed - it was the broken links that were causing the client to create dupes.
Tested on kokua 0.1.0 WIP and SL 2.6.3. I now have no problems managing outfits on my standalone.
