BUR #6588 has been approved by @nonamethanks.
create alias laevatein -> laevatein_(touhou)
rename laevateinn -> laevateinn_(sword_girls)
Laevateinn is a mythological weapon, but currently the tag is only being used for it's Touhou appearance.
Plus disambiguates from laevatein_(fire_emblem).
Not including Spear the Gungnir in the BUR since the name is clear enough from "Gungnir".
EDIT: does laevatein_(tail) need disambiguation too?
