Title: ignore empty subject tags in CSWGetRecords parser

When having empty dc:subject tags in the response, the parser currently creates an Array with objects which have a value of an empty string, so [{value: ""}, {value: ""}]. When rendered in an Ext grid, this will yield "," in the cell. I think it's better to ignore empty tags in the OpenLayers Format already, and that's what this patch does. TIA for any review.
