Fix upgradeInsecureRequests CSP directive
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

Add missing unsafe-inline CSP directive
Dropbox loads an external script that adds inline javascript. Therefore, this addition is needed when enabling dropbox support.

Add dropbox CSP directive if configured and make button clickable
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.

Update RevealJS to version 3.9.2
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:

Fix broken Gist embedding
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`.

Fix disqus CSP
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.

Fix CSP for speaker notes
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.

Add data: URL to CSP and upgrade helmet
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.

Fix CSP for disqus and Google Analytics
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.

Allow embedding of video and audio tags
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.
