The `upgradeInsecureRequests` option of Helmets CSP middleware
was a boolean in Helmet 3, but with Helmet 4,
everything changed to lists.
This commit adjusts the addUpgradeUnsafeRequestsOptionTo
function accordingly.
Closes#1221

Dropbox loads an external script that adds inline javascript. Therefore, this addition is needed when enabling dropbox support.

The lack of a 'preventDefault' on the click event handler resulted in the dropbox link being unclickable.
Furthermore because of a missing CSP rule, the dropbox script couldn't be loaded. The dropbox origin is now added to the CSP script sources if dropbox integration is configured.

This update of revealJS helps us to get rid of the headjs depedency
integration using webpack. It updates reveal.js to 3.9.2 and updates the
csp hash accordingly for using the slide mode.
Background for this update is the critical security vulnerability
described by snyk in their disclosure:

Looks like GitHub changed their asset system and our CSP prevented them
from getting loaded.
This patch should fix the Gist embedding with enabled CSP by replacing
the old URL `https://assets-cdn.github.com` with the new
`https://github.githubassets.com`.

Disqus loads it's embed config.js from its root domain
(https://disqus.com). Our CSPs only allow subdomains (e.g.:
https://codimd.disqus.com). This causes the disqus embedding to fail.
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.

Looks like I was wrong in my previous commit to update revealjs.[1]
The speaker notes broke again with the CSPs. So this patch updates the
hash and this way the speaker notes.

Seems like the old version of helmet had a problem with `data:`. This
patch upgrades to the latest version and adds the CSP rule to allow
Google Fonts and the offline version of it, to properly include the
fonts and no longer throw ugly error messages at us.

This commit should fix existing problems with Disqus and Google
Analytics enabled in the meta-yaml section of a note.
Before this commit they were blocked by the strict CSP. It's still
possible to disable the added directives using `addDisqus` and
`addGoogleAnalytics` in the `csp` config section.
They are enabled by default to prevent breaking changes.

Adding mediaSrc to CSP so video and audio files can be embedded without
problems.
From a security perspective it should be fine to load audio and video
data without introducing a high security issue. Only from a privacy
perspective it allows another way to track users if there are data
embedded. But it doesn't introduce any new attack vector as pictures are
also allowed from everywhere.

This refactors the configs a bit to now use camel case everywhere.
This change should help to clean up the config interface and make it
better understandable.

This option is needed as it's currently not possible to add an report
URI by the directives array. This option also allows to get CSP reports
not only on docker based setup but also on our heroku instances.
