Alias request Master_Eraqus and Master_Xehanort -> Eraqus and Xehanort

BUR #18865 has been rejected.

create alias master_eraqus -> eraqus
create alias master_xehanort -> xehanort

They're the same characters. Eraqus was introduced only as "Master Eraqus" in earlier games, but more recent games show a younger version of him without the "Master" title. Since it's not part of their actual, legal names, and we don't call other characters like Aqua "Master Aqua" despite her also being a keyblade master, it makes sense to merge the tags.

The wikis say they're for the old and young versions, a la Joseph Joestar (Old) / Joseph Joestar (Young).
