minor modifications

Here are a couple of tweaks to the development website:

jdbc.patch

Point the download target for JDBC to be jdbc.postgresql.org instead of
gborg. In general I found it a little confusing how interfaces
(http://wwwmaster.postgresql.org/docs/interfaces) and downloads matched up
pretty closely, but not quite.

irc.patch

Rename rooms to channels, add linked urls ("irc://") and mention french
and spanish specific channels.

developer.patch

Add the build farm to the list of testing resources. Rename Tools to CVS
and replace the dead interfaces repository with a link to instructions on
how to retrieve the cvs repository.

Finally I notice there are a number of files with window EOL characters in
the repository.
