    Quick hack that uses the (mobile) browser's geolocation API to update the
    beacon sensor (not part of the spaceAPI yet at the time of writing)
    Simply navigate to:
        geo.php?key=<API_KEY>&address=<SENSOR_ADDRESS>
    where <API_KEY> is the API key defined in index.php
    and <SENSOR_ADDRESS> is the name of the beacon sensor to set or update
