Topic: Un-alias revenant -> character:revenant

This is a bit of a weird one.
Currently revenant defaults to a character tag, when the current usage may be more suited to a species tag.

The other half of the problem is that I discovered this on an irrelevant image, due to someone attempting to tag the Guild Wars 2 class of the same name.
This incorrectly glued undead to the image until I realised revenant was applied as a character tag.
