Fix cross browser issues for responseXML

- IE8 doesn't support indexOf, use our own arrayContains
- Most browsers don't allow 'text/html' when using a DOMParser, so we
  won't support it for now.
- Firefox doesn't want to serialize Documents over selenium, so don't
  have them in as our expected, just use instanceof ourselves
