Added support for attributes in <cas:serviceResponse>:

Need to be enabled in config/module_casserver.php with:

'attributes' => TRUE,

The 'schema' is:

<cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
  <cas:authenticationSuccess>
    <cas:user>xxx</cas:user>
    <cas:attributes>
      <cas:foo>bar</cas:foo>
      <cas:foo>baz</cas:foo>
    </cas:attributes>
  </cas:authenticationSuccess>
</cas:serviceResponse>

where foo is the attribute name and bar,baz are the values.
