EXT-3958 title needs to update appropriately when changes made to outfit

We now show a string "(unsaved)" under the appearance panel outfit title
when the currently loaded outfit has been modified from its original state.

Tested with following conditions:
1) item added to loaded outfit
2) item removed from loaded outfit
3) item replaced in loaded outfit

Appears to work properly on login as well. Checking is a manual folder compare,
but should be fairly efficient.
