EXT-7722 Fixed "Add to COF" and "Remove from COF" outfit context menu items to be enabled when appropriate and work properly.
Work on "Take Off - Remove from Current Outfit" and "Wear - Add to Current Outfit" menu options:
- The menu items of the outfit context menu and the My Outfits gear menu are now disabled
when inappropriate instead of being hidden.
- The menu items get enabled/disabled depending on whether you can wear (take off) anything from the selected outfit.
(was: depending on whether you're wearing the outfit)
- Changed the way the options work: they now only operate on clothes and attachments.
"Add to COF" now only adds those body parts that are missing in COF;
"Remove from COF" doesn't touch body parts at all.
Without this change both "Add" and "Remove" options would be available simultaneously, because
any valid outfit contains body parts. I think that would be confusing.
And you don't expect you body parts to be replaced when doing "Add to COF'. (that's addition, not replacement)
