[text] Merge the attributes with markup enabled
ClutterText should merge the PangoAttributes set by using clutter_text_set_attributes() with the attributes generated by parsing Pango markup. For this to work we must parse the markup and merge the attributes we get out of pango_parse_markup() with the attributes set by the user. Setting the markup or the attributes on an editable text should not work for the time being.
