Fixes for TitleCleanup subclasses:

Fixes for TitleCleanup subclasses:

* (r56711) Don't use unbufferred queries unless someone is holding a gun to your head, they cause no end of trouble. Use batched queries instead. Should fix the bug reported on bug 20741 comment 13.
* Fixed a bug in cleanupTitles.php which caused it to fail to convert spaces in page_title to underscores, possibly caused by r6355.
* Made cleanupWatchlist.php respect "--fix" as documented
* Made runTable accept a parameter array instead of an ever-growing formal parameter list
* Renamed processPage() to more accurate processRow(). Removed abstract function definition since the name of the function can be overridden.
* Made a few things public instead of protected for easier testing via eval.php
* Fixed missing newlines in progress messages in cleanupCaps.php
