/* jQuery.preloader - v0.95 - K Reeve aka BinaryKitten
*
* v0.95
*   # Note - keeping below v1 as really not sure that I consider it public usable.
*   # But it saying that it does the job it was intended to do.
*   Added Completion of loading callback.
*   Main Reworking With Thanks to Remy Sharp of jQuery for Designers
*
*
* v0.9
*   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
