Message:

Added support for file transfer with the desktop. Each Rappture
application acts like an http server, configured to listen on
a particular port according to the parameters found in the file
~/data/sessions/$SESSION/resources. When the server is active,
the GUI has a "Download..." button in the results area. A Java
client (in the filexfer directory) connects to the server and
listens for download requests. When the user clicks on "Download...",
the desired result is spooled to a file, and a Java client pops up
a web page requesting the file. This downloads the result to the
user's desktop.

Note that if the $SESSION environment variable is not set, these
changes do nothing.
