Filefield Display Filter

Issue Summary

I'm looking through this module and trying to decide if it does what I want it to do or not, and I was thinking, "What it really needs is to provide a filefield display filter!". Kind of like the MP3Player module, just provide a way to use the FreeMind applet and display the contents of a Filefield.

If this is in the works, let me know, otherwise I might roll my own. Can't guarantee it will be a patch or not (I don't need anything else, and I have so many modules already in place without tossing in Node Hierarchy...), but it would be easy enough to integrate.

Cool project, FreeMind rocks.
