create alias for the following tags:
okita_souji_(fate)_(cosplay) > okita_souji_(koha/ace)_(cosplay)
jeanne_d'arc_(fate)_(cosplay) > jeanne_d'arc_(fate/apocrypha)_(cosplay)
nero_claudius_(fate)_(cosplay) > nero_claudius_(fate/extra)_(cosplay)
I noticed that while in the shuffle of removing the "_(all)" suffix from the tags nobody bothered to modify the corresponding cosplay tags to match the new designations.
