Disqus loads it's embed config.js from its root domain
(https://disqus.com). Our CSPs only allow subdomains (e.g.:

This patch should fix this problem by adding https://disqus.com to the
CSP setting. From a security perspective there is no real change. Since
still the same parties are involved.

A refactoring towards another password algorithm was worked on and this
is probably still the way to go. But for now the successor of our
previous library should already be enough.

It seems like the inital work on the hsts module expected milliseconds.
This has either changed or was never true. Either way, it caused that
the current defaults resulted in theory in a 1000 year HSTS policy.
Luckily helmet was smart enough to not go higher than 1 year.
Anyway, this patch fixes the multiplication of the configured size with
1000 by removing this multiplication.
Also to simplify the reading of the defaults, we split them into their
components, 60 times 60 seconds so we get one hour. 24 of those hours so
we get a day and finally 365 days to get our original wanted default of
one year.

During the upgrade of winston in
c3584770f2 a the class extension for
streaming was removed.
This caused silent crashes. Somehow winston simply called
`process.exit(1)` whenever `logger.write()` was called. This is really
bad and only easy to debug because of the testing right after upgrading.
However, reimplementing the stream interface as it was, didn't work, due
to the fact that `logger.write()` is already implemented and causes the
mentioned problem. So we extent the object with an `stream` object that
implements `write()` for streams and pass that to morgan.
So this patch fixes unexpected exiting for streaming towards our logging
module.
