Merge maintenance-work branch (now with less errors!):

* Docs have been updated to indicate the standard on how to write maintenance scripts (MW.org docs will follow) Have ported vast majority of maintenance scripts to new format. Remaining ones (mostly FiveUpgrade-related) are a bit more tricky. commandLine.inc is untouched for now. Many have gotten code-style updates as well. Deleted .inc files were only used by their .php counterparts, and have been merged into single files.
* (bug 11867) Lock error on redirect table when running orphans.php
* (bug 16322) Allow maintenance scripts to accept DB user/pass over input or params
* (bug 18566) Maintenance script to un/protect pages
* initStats overhaul, now uses class SiteStatsInit. Also fixes bug 18930
