* 	Main Reworking With Thanks to Remy Sharp of jQuery for Designers
*
*

* 	Fixed .toString being .toSteing
*
* v0.8
*		Fixed sheet.href being null error (was causing issues in FF3RC1)
*
* v0.7
*		Remade the preLoadImages from jQuery to DOM
*
* v0.6
* 		Fixed IE6 Compatability!
*		Moved from jQuery to DOM
*
* v0.5
* 		Shifted the additionalimages loader in the preLoadAllImages so it wasn't called multiple times
* 		Created secondary .preLoadImages to handle additionalimages and so it can be called on itself
