	NOTES:
 
	* make it only apply on mediawiki/user pages that end with a lowercase ".js"
	* un-comment out vars
	* join into a single '(function() {}();' and make everything look tidier
	* fix the html of #source-highlight (sometimes only replaces a character like [&<>] with only the beginning of its entity)
