mod_auth_ccert/README: Add setting to ensure Prosdy asks for client certificate This used to be the default for all services, but since it triggers annoying popups in web browsers it was inverted in Prosody and only s2s enables it, so it needs to be explicitly enabled for c2s again. See trunk 115b5e32d960 Thanks debacle

This module produces more detailed HTTP logs for Prosodys built-in HTTP
server. The format is similar to that of Apache and go into Prosodys
normal logs at the `info` level.
