A bunch of aliases for *_clothing -> *_clothes

Posted under Tags

BUR #10232 has been approved by @evazion.

create alias slavic_clothing -> slavic_clothes
create alias female_ejaculation_through_clothing -> female_ejaculation_through_clothes
create alias layered_clothing -> layered_clothes
create alias tribadism_through_clothing -> tribadism_through_clothes
create alias masturbation_through_clothing -> masturbation_through_clothes

The vast majority of tags regarding clothing use the words clothes, as seen here and here. The few exceptions left over should be standardized.

There are some left-over tags that are already aliases or deleted, so I don't think they're that big of a deal. Still, those five need the most attention.
