This does some more in depth check on the error message and minimizes
the log noise that is caused by LZString.

Right now we still see a lot of LZString parsing errors in the logs.
They probably come from the user history. We should minimize the number
by add the basic length check there as well.

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

From a security perspective it should be fine to load audio and video

embedded. But it doesn't introduce any new attack vector as pictures are

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.
