search: support negated wildcards in post searches.

Browse Source 
* Support negated wildcards in searches (e.g. "holding -holding_*")
* Raise wildcard limit to matching 25 tags regardless of user level.
* Fix wildcards potentially matching empty tags.
* Fix wildcard tags being sorted by post count only, and therefore not
  having a stable ordering when tags have equal post counts.
* Fix sidebar to calculate wildcards tags the same way the search does.
