[releng] Fix

[Michael Catanzaro <mcatanzaro src gnome org>]

commit 35e6722f1efc1a50c57b27603584b7ecd0039e62
Author: Michael Catanzaro <mcatanzaro gnome org>

    Fix
    
    I broke the HTML parser in 62c85310, so now only tarballs available via
    SFTP can be downloaded. Update by properly revising our urllister class
    to overload an HTMLParser method rather than an SGMLParser method.
    
    Fixes #13
