Work in progress on saving exported solutions to
server instead of to file.  Doesn't work yet.
The idea is to have save to file if server save doesn't
work.
Export now saves to server.  If save to server fails,
then it saves to file.  Issues:
1. Status bit is not set in java code.
2. If I have previously exported the solution in
  a session, then there is a java error saying that the
  document tree already exists.  Need to destroy the document
  tree after export.
3. I have only tested this on my local maching (OS X) so
   I haven't verified this on the devel server.
Add script available_problems.php
and allowed pass through of forum name through
java application.
Still need to add forum flag to jnlp
and to solutions table.
