add a old directory at ftp.gnu.org/gnu/classpathx/

Hi all,

I'm updating activation, and mail debian packages and I have a little
problem with detecting new release because of
'activation-20040420.tar.gz' and 'mail-20040420.tar.gz'. What about
creating a new 'old' directory and put these releases under that
directory. We can keep the last or the two last releases in the main
directory.

Comment?
