Adds @ to faux_path template variable
Update tests for strict variable testing
Add param to ctrl purging of vhost dir
Allow ssl_certs_dir to be unset.

In some cases we don't want SSLCACertificatePath to be set at all.

might want that to be the only CA used. Most other options in this
template are optional, so I don't see why this one can't be too.
