Issue: Search UI

Use the Search for vB3 blogs for inspiration. It's a much more concise solution than stock vB3 search. Once both are done, see if we can genericize as many methods as possible. It really bothers me having so many solutions for search that need to be rewritten for every platform.

The big stuff is handled now (query processing and indexing). Tomorrow I will wrap up the vB3 side, and share methods with vB4 where possible. Then I'll generate a vB3 index (on vB4!) and test. If all goes well, I look forward to moving on to adding live-search to the sidebar.

Okay search is confirmed working now, and I've gone ahead and fixed everything that broke while working on it (like every page-list, datastore, and last update bit). Seems queries creeped back up sometime in the last month. I'll deal with that once everything actually works again (pointless to reduce queries that might need changing soon anyway).

Further search method consolidation tomorrow, and live search.

Consolidation and cleanup complete. vB4 search also confirmed working. Now to start on the fun wiki search feature!

Live search finished and confirmed working. Marking issue as completed for 4.0.0 Alpha 1.
