Title: Added RDFa support for browse/node

RDFa allows HTML to contain rich semantics. The RDFa added here allows for RDFa-aware processors to extract the latitude and longitude of points.

The vocabulary used is the W3C's Basic Geo WGS84 vocabulary available at . This vocabulary is in widespread use (for instance, on dbpedia.org, an RDF
version of Wikipedia).

RDFa works perfectly well with the existing geo microformat.
