Subject: [PATCH] Revert most of failed experiment but keep the good parts.

- tag_autocomplete.tags and .synonyms are separate vars, not in tagset.
- tag_autocomplete.tags is now a Set object for faster resolve().
- get_all_tags moved to api.js.
- server provides "updated" timestamp with the all_tags list.
