Support for line breaks between KML coordinate tuples

I was trying to parse some KML files with geoPHP today and it kept throwing exceptions because the coordinate tuples in a LineString were separated with line breaks, not spaces. Google's KML reference says to use spaces, but they also provide examples where line breaks are used (see https://developers.google.com/kml/documentation/kml_tut#paths).

This might not be a legitimate issue, but I figured I'd send it in since almost every sample KML file out there seems to use line breaks.
