Add support for the new Nokia REST API to nokia plugin.

Support is added in such a way that both the v1 and v2 REST APIs are
supported by the plugin.  By default the v1 API is used.  The
application developer can explicitly select v2 by setting the
places.api_version plugin parameter to 2.  At some point the default
will change to v2 and support for v1 and places.api_version may be
dropped entirely.

The new REST API is documented at
http://api.places.lbs.maps.nokia.com/places/static/doc/index.html
