Sets the regular expression that URL's are checked against. Including the
C<url( )> wrapper. You are encouraged to use this method to provide a regexp
that will only allow URL's to domains you control:

 CSS::Adaptor::Whitelist::set_url_re(qr{url(https?://example\.com/[\w/]+)});

Notice that the regexp should not be anchored (no C<^> and C<$> at the edges).
It is being used in these properties:

 cursor
 background
 background-image
 list-style
 list-style-image

=item log

This is a method that stores messages of things being filtered out in
the C<@CSS::Adaptor::Whitelist::message_log> array.
