Pool to tag: Grey Underwear; then, some tag implications

Pool to tag: pool #97 "Grey Underwear" to grey_underwear

Tag implications:

• grey_bra -> grey_underwear
• grey_panties -> grey_underwear

Reasons: Because the concept of "grey underwear" is a simple, straightforward, objective color-thing combination, and the implicated tags are grey underwear too.

Unless we want to establish *_underwear tags for every color, the pool will just be deleted without any implications.
If we want them, we'd have to properly define underwear (forum #67041).

Deleted the pool. If we do them, they'd be tags.
