By ending with "Start" we can create a sensibly named "mwLoadEnd".
Also calling it LoadStart instead of StartUp so that it matches
the mediaWikiLoadStart global.
Abandoning 'mediaWiki' as prefix since that's a left-over from the
mediawiki.js global variable, as abbreviation 'mw' makes more sense
or full on 'MediaWiki' (with proper capital 'M').
