Subject: [PATCH] GeoPointParserUtil.getQueryParameters() to return Map of all
 parameters

This parses out all of the parameters in the query string for both http:
and geo: URIs.  This will only work on URIs with valid syntax, so it will
not work on URIs that do odd things like have a query string in the
fragment, like this one:
