converting general tags to meta tags

BUR #2541 has been approved by @evazion.

category crease -> meta
create implication crease -> scan
create implication novel_illustration -> official_art

Reason: crease is comparable to tags like scan artifacts and jpeg artifacts.
The *_cover and circle_cut tags describe the format, context and purpose of the overall image, and could be meta tags as well. This would also help differentiate these tags from presence-of-object tags like record jacket, manga_(object), etc.

The first implication seems reasonable to me. There might be instances of "fake creases" for artistic effect though. Likewise, the latter two implications might not be correct if "fake novel covers" are a thing.

EDIT: request updated based on feedback

Fake magazine cover implies magazine cover, I'm not sure if those images should have a meta tag on them.

There are also fake novel covers under the novel cover tag (eg. post #1651713). It wouldn't surprise me if the same was true of the other *_cover tags. Also, novel illustration is supposed to be for illustrations from inside the novel, ie. specifically not the cover.

There is quite a bit of overlap as a lot of light novels contain textless versions of the cover image inside the novel, but stuff like post #3863471 and post #3851302 should not be given the novel illustration tag. Glimpsing through, nor should about half of the stuff with both tags...

+1 to the implication of novel_illustration to official art, though (although doing would be another reason not to imply novel_cover to novel_illustration).

Just for the reconrd, we have cover_image for textless cover images, but it's often forgotten (by me too).
