Fixes a minor map issue by using openstreetmap.org

The previous map was badly zoomed and location couldn't be verified
correctly for most of peoples. The new version corrected that issue and
uses embeded map from openstreetmap.org that is a free system instead of
google maps (and also the Gmaps version was created by printscrean I
think!)
