There were parts of this code that were sticking in a URL-encoded query
string into GeoParsedPoint, and other parts that were putting in a regular
non-URL-encoded String. This meant that URLs with an & in the query string
encoded as %26 were not being properly parsed, since & is used to split up
the query string. That also makes it impossible to output a properly
encoded URI from getGeoUriString().
