pgfoundry references in docs

Attached are two patches, one of which I'd like to apply. Open for
discussion on which one.

The smaller one, pgfoundry_1.diff, removes the suggestion to apply for
new projects on pgfoundry. The reason for this being that pgfoundry
doesn't *accept* new projects anymore.

The second one removes the reference to pgfoundry completely. As a
step in the deprecation.

I'd prefer to apply the second one, but will settle for the first one
if people object ;)
