Title: Updating _xhrTransport to support File upload

Made FileUploader._xhrTransport a bit more intelligent about the type of upload to be performed. If form data was provided for the item, then a FormData upload is made, else a simple File upload is performed instead. This gives the browser a chance to correctly set the Expect: 100-continue header for large files (a big deal for storage servers that may need a chance to do special processing for larger files).
