extend http-equiv parsing to handle redirects without url=

On some site (m.bahn.de) the meta element looked like this:

<meta http-equiv="Refresh" content="0;http://www.bahn.de/m/;fitScript=0/">

To handle the missing 'url=' in the content attribute we extend the
parsing to skip beyond the ';' in case there is no 'url='
