Title: Implement a new authentication method based on SSL client certificates.

I propose an additional authentication method based on SSL client certificates.

This patch shall serve as a quick and dirty proof of concept. Further discussion very welcome.

The basis for this implementation is my personnel setup where Apache denies the SSL handshake at all if the user does not provide a valid certificate.
