SWFUpload Code

Fixed IE problems (at least IE 7 with my version of Flash) where the upload was not allowed and the server response was not being processed.
In the process of moving away from LocalConnection to SharedObjects for image preview transfer because LC is too slow in IE.
Work on making the button image zoomable. Text will not be zoomable.

Memory cleanup in SWFUpload. Now disposes the Multipart uploader after completion and/or errors.
Unloads the loader after it's data is retrieved for the resize.
