As a temporary fix, to keep you and your users save, this patch disables
the PDF export feature. Details of the attack along with a fix for
future versions of CodiMD will be released in future.
I hope you can live with this solution for this release because I'm
super short on time and the alternative would be to ship no fix at all.
This appears to be the better solution for this release.

Do Not Track (DNT) is an old web standard in order to notify pages that
the user doesn't want to be tracked. Even while a lot of pages either
ignore this header or even worse, use it for tracking purposes, the
orignal intention of this header is good and should be adopted.
This patch implements a respect of the DNT header by no longer including
the optional Google Analytics and disqus integrations when sending a DNT
header. This should reduce outside resource usage and help to stay more
private.
This should later-on extended towards other document content (i.e.
iframe based content).
The reason to not change the CDN handling is that CDNs will be
deprecated with next release and removed in long term.

We have various places with overly simple if statements that could be

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.
