SkinController is adding paid and approved in-game skins

The /preloadskins command in SkinController is adding paid and approved in-game skins, which it shouldn’t be doing.

The /addskin, /addcollection, and /importskins commands don’t seem to filter out approved or DLC skins either, which adds to the issue.

There also doesn’t appear to be a command to check for or remove these skins once they’re in. Since Facepunch keeps updating the approved list, having a way to clean them out would be really useful.
