Add global authentication

This commit adds global authentication to binder to ensure that only valid
users are able to use it. This should enable binder to be used in
environemts where it's webfrontend is reachable for unauthenticated users as
well.

For setups where such a global authentication isn't desired it can be disabled
by simply removing the LoginRequiredMiddleware from the list of active
middlewares.
