Reorganization of SearchEngine for legibility

* Removed 'fuzzy title search', it's not been maintained and generally produces unexpected and unwanted results
* Separated search guts (in SearchEngine) from display/control (in SpecialSearch)
* Extracted MySQL3 and MySQL4 variants to subclasses
* Added PHPUnit tests for MySQL3 and MySQL4 search engines, which try to use temporary tables to fiddle in (if configured)
* comments n stuff
