HedgeDoc displays the username and user photo at various places
by rendering the respective variables into an `ejs` template.
As the values are user-provided or generated from user-provided data,
it may be possible to inject unwanted HTML.
This commit sanitizes the username and photo URL by passing them
through the `xss` library.

This polyfill was added because node versions less than 10.5.0 didn't include scrypt support. As we now raised the minimum required version to 12.0.0, this polyfill isn't needed anymore.

Currently a problem appears when using OpenID for authentication as
there is no method to add a profile picture right now.
This patch makes sure that all undefined login methods get a profile
picture.

Since our previous scrypt library is unmaintained since 3 years, it's
time to look for an alternative.
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.

privacy perspective, forbidding it allows to improve privacy.

In the current setup users could be tricked into deleting their data by
providing a malicious link like `[click me](/me/delete)`. This commit
prevents such an easy attack and need the user's deleteToken to get his
data deleted. In case someone requests his deletion by email you can
also ask him for this token.
We can add a GUI that shows it later on.

To prevent further weakening of our CSP policies, moving the Avatars
into a non-inline version is the way to go.
This implementation probably needs some beautification. But already fixes
the bug.
