#2 patches for 1.16 fail

[jason]

patches for 1.16 version of mediawiki fail, and v1.15 files are all empty in current distributed source code.

In 1.16 CategoryPage.php there are no functions called addPage, addSubcategory, addSubcategoryOptions... etc.
I didn't check all files, but SpecialAllpages.php doesn't seem to work either. If these don't work, the others probably don't work as well.
We are patching against the distributed source code for mediawiki: http://download.wikimedia.org/mediawiki/1.6/mediawiki-1.6.12.tar.gz
