1.2.2

The admin screen's page slug is user-tags again.

Renaming the text domain to user-tags-lib in 1.2.0 had swallowed Menu::SLUG, because they were the same string. The menu link pointed at users.php?page=user-tags-lib, and anyone following a bookmark or a link built from the documented slug got Sorry, you are not allowed to access this page.

No test caught it — they all went through Menu::url(), which was internally consistent with the mistake. One now pins the slug itself, and records why the two are different things: one is a URL, the other has to match a wordpress.org slug.
