Update qcssscanner so it can parse our normal offline documentation CSS

Adds the three CSS3 attribute selectors.

During this the internal naming of the existing attribute-selectors have
been changed to be more clear, and the dash-matching has been fixed to
not just be beginsWith.

A non-breaking space have also been removed from the CSS.
