* remove require_once() throughout whole code, yet left in few places
* move global functions in HttpUtils, ProxyTools, Credits to class methods
* php5 only: __autoload() now used, combined with class->file map and require()
* move initialization of $wgValidSkinNames to Skin::getSkinNames()
* few more changes that will surely break stuff.
updating the searchindex:
UPDATE `Array` SET si_title='page 1' WHERE si_page='2910'
from within function "SearchMySQL4::updateTitle". MySQL returned error
"1146: Table 'HEAD.Array' doesn't exist (localhost)".
The new query causes the following to be executed:
UPDATE `searchindex` SET si_title='page 1' WHERE si_page='2909'
(somebody more familiar with the the whole searchindexing code please review
the while move process)
