[Using Sakai] File type for uploaded files

[Mike Jennings]

We have seen this issue happen when the browser mime types in firefox 
that have been corrupted for some reason.

We use this simple cgi/html upload checker to see what mime type is 
associated with the upload

==> upload.cgi <==
#!/bin/sh
echo 'Content-Type: text/plain'
echo
exec 2>&1
set -x
grep -aim1 content-type

==> upload.html <==
<form enctype="multipart/form-data" action="upload.cgi" method="POST">
     <input name="file" type="file" />
     <input type="submit" />
</form>

In firefox you can reset your memtypes by delete the mimeTypes.rdf file 
from the users firefox profile.
