BUR #20822 has been approved by @evazion.
create alias coffee_maker_(object) -> coffee_maker
This tag used to be called just coffee maker, but at some point a user renamed the tag to coffee maker (object) so they could use coffee maker as an artist tag. That artist has since been moved to hatimitu0002, so we can safely rename coffee maker to exclude the dubious qualifier.
This has to be an alias and not a rename because it has more than 200 posts.
