Website is now https only - please help with testing

As some were briefed about during the pginfra session at pgcon, we have now
configured the www.postgresql.org website to be https only.

Any access with http should result in a redirect to https only. We will be
deploying http strict transport security at a later date, once we have had
more testing.

Speaking of testing, we'd appreciate help from others with testing the site
out at this point. Please let us know anything that does not work properly
for you (especially if related to https, but please report other issues as
well, as they might be "silently dependent" on the change through other
backend changes bundled up with it)
