Authorisation

For now http basic auth is used. If you try to login with user, which does not exist, it will be automatically created. First created receives admin rights. Others only receive them when someone with admin rights confirms, it's okay.

Consider, if you are okay with passing your passwords using plain HTTP.

If you don't need auth, you can disable it by --no-auth command-line option.
