create alias kyuubi_(naruto) -> kurama_(naruto)
They're the same character.
http://naruto.wikia.com/wiki/Kurama
"Kurama" is the proper name while "Kyuubi" simply means "nine tails".
An alias, rather than a retagging, is needed because both names are widely known among the fanbase.
EDIT: This tag alias has been rejected because it was not approved within 60 days.
