feat(wpmc 1.1.0): Redirect::handle reverse-slug lookup on is_404

Browse Source 
Replace old triggering-on-page_new semantics with washanyanya-style:
- template_redirect@1 + is_404() trigger
- get_posts(name=$slug, post_type=page, status=[private,publish])
- match candidate.ID against page_unic[i].page_new
- 301 to /<town>/<orig-canonical-path>/

Closes Gitea issue #1.
