[PATCH] add link to bugs mailing list to web site

[Garrett Rooney <ro...@electricjellyfish.net>]

It turns out we don't have a link to the bugs mailing list on the web 
page.  It took me a little while to figure out that comments on APR bugs 
in bugzilla were being sent to the httpd bugs list.  I'm not sure if 
that's really the best thing (wouldn't it make more sense to have an APR 
bugs list, since it's a separate project?), but as long as it is the 
case we should at least point people to it.

Here's a patch against the version of the site in apr-site's trunk.

Note that it also includes some changes to mailing-lists.html that 
result from the previous change to mailing-lists.xml, since it seems 
that mailing-lists.html wasn't updated when the previous change was 
committed.
