remove alias cait_sith_(ff7) -> cait_sith_(final_fantasy)
Much like Mog before, Cait Sith is the name of several unrelated characters in Final Fantasy, and it makes little sense to cram them all into one tag. This is not like the case of recurring summons like Ifrit or Shiva (which are merely different designs for each game); Cait Sith is presented differently in each game. He's been a summon in VI and XI, an NPC in XIV, a playable character in VII, and a plush wielded by Lulu in X. The Cait Sith from VII in particular has many costumes that are not implied to the main tag yet, and Revelation will probably bring more, so this is a good time to deal with it.
Removing the alias is the first step. Then it depends on whether we want an umbrella tag, or get rid of the tag altogether so that each incarnation can have its own separate tag. I already made the tags for the others: Cait sith (ff6), Cait Sith (ff10), Cait Sith (ff11), Cait Sith (ff14)
