when we get a non-file dropped, check to see if any applets support any of the mimetypes in the drop. if so, create a tempfile with the data in it and start the applet with that data. it's pretty ... interesting to drop web content from a webbrowser onto the desktop and get a miniwebrowser showing the results.
