This will make the attachment button functional. When the button is pressed the selected file will be uploaded via. HTTP File Upload. The download link can only be get by copying it from the XML log. The link won't be sent into a message nor into a SIMS element. Also the HttpUploadHandler has been renamed to UploadHandler, because it should handle general file uploading, not limited to HTTP File Upload. Probably also jingle sessions for SIMS will be created in there, later.
