Hey Hubot! Geocode this!

I need the lat/lon of random places fairly often, except i'm a little too lazy to open getlatlon.com or drop a lat/lon marker in Google Maps. So I drafted in Hubot to help me out.

Either `where is` or `geocode me` can be used in phrasing to Hubot. The Google Maps API is used to locate places, so there is a daily per IP limit, but this is fairly high for Hubots usage.
