feature request: share with openstreetmap

[freddii]

at the moment when you share your location from menu you get a link like:
http://maps.google.com/?q=52.5000,13.4000&z=10

maybe a better link would be:
https://www.google.com/maps/place/@52.5000,13.4000,10z

it would be nice to share by default with openstreetmap:
http://www.openstreetmap.org/#map=10/52.5000/13.4000

also add an option to switch between openstreetmap and google-maps in settings menu
