Add google maps navigation

[gdesmott]

Would be cool to be able to start google maps and let it navigate you to a restaurant.

So I tried this: https://github.com/gdesmott/vegout/commit/9c712326edce5bb62c84b4c6eeeaf2dd20a5cf76

generating this kind of URL: https://maps.google.com/maps?saddr=my+location&daddr=50.8485475,4.3469062001

it works fine on desktop, but on Android it doesn't parse "my location" as an address and the coords are converted to 50,8485475,4,3469062001 which obviously doesn't work. :\

Looks like if we don't pass any saddr Google Maps does the right thing on Android which is the most important use case. Closing.
