mod_auth_ccert/README: Add certificate purpose conifg to example Thanks debacle By default Prosody validates all client certificates as if they were server certificates, for historical reasons, from a time when you couldn't get certificates with the client purpose.

This module produces more detailed HTTP logs for Prosodys built-in HTTP

normal logs at the `info` level.
