BUR #15253 has been approved by @evazion.
rename touhou_(game) -> touhou_user_interface
Touhou (game) is a very ambiguous tag that you'd assume is an umbrella tag for the games, but it's actually a tag for the UI from the games. This should have a less ambiguous name and be a general tag instead, similar to SRW battle screen and Pokemon battle. BUR won't let me set touhou user interface to a gentag since it doesn't exist yet, so it'll just have to be changed if this goes through.
