If output buffering is turned on, PHP can be a bit slack about sending
the data to the client before closing the connection with exit(). These
changes ensure we call ob_flush() before we leave. We call @ob_flush()
so we don't get noisy warnings when output buffering is off...

CalDAVPrincipal class with a new DAVPrincipal class which extends
the Principal class.

such as LDAP, although I have endeavoured to resolve those
potential issues.
