As it turns out, if the serverURL can't be generated correctly, HackMD
will use relative paths in image upload. This causes broken links in
PDF.
With this commit we force absolute links during PDF creation which
hopefully fixes the problem.

This is caused by a relative path in our upload routine. This change

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 be GDPR compliant we need to provide privacy statement. These should
be linked on the index page. So as soon as a document exist under
`public/docs/privacy.md` the link will show up.
Since we already add legal links, we also add Terms of Use, which will
show up as soon as `public/docs/terms-of-use.md` exists.
This should allow everyone to provide the legal documents they need for
GDPR and other privacy and business laws.

Currently the session secret can only be set by config.json or docker
secrets. This creates a problem on Heroku hosted instances that can not
set a session secret.
Since we automatically generate them on startup this results in an
logout of all users on every config change in Heroku.

We should check for an undefined and not just for a logical true or
false.
Example: When `usecdn` was set to false it was impossible to overwrite
the new config value because the if statement becomes false.

The session secret is used to sign and authenticate the session cookie
and this way very important for the authentication process.
By default the session secret is set to `secret` and never changes. This
commit will add a generator for a dynamic session secret if it stays
unchanged.
It prevents session hijacking this way and will warn the user about
the missing secret.
This also implies that on a restart without configured session secret
will log out all users. While it may seems annoying, it's for the users
best.

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 should make the imageRouter more modular and easier to extent. Also
a lot of code duplication was removed which should simplify maintenance
in future.
In the new setup we only need to provide a new module file which exports
a function called `uploadImage` and takes a filePath and a callback as
argument. The callback itself takes an error and an url as parameter.
This eliminates the need of a try-catch-block around the statement and
re-enabled the optimization in NodeJS.

This check is needed at there are tons of LDAP implementations out there
and none has at least one guaranteed unique field. As we currently check
three fields and added an option to select one yourself, it's still not

This determines which ldap field is used as the username on
HackMD. By default, the "id" is used as username, too. The id
is taken from the fields `uidNumber`, `uid` or
`sAMAccountName`. To give the user more flexibility, they can
now choose the field used for the username instead.
