Geolocate does not show a marker on your current location

Though geolocate pans the map to the user's current location, it doesn't pinpoint exactly where the user is located. A marker dropped at the current location would help here.

Tracking upstream mapbox/mapbox-gl-js#2692

[lucaswoj]

Just commented on the upstream issue. The Geocoder control is intended to be more general and more flexible, to the point that it could be used without a map. I suggest implementing this behaviour downstream. We plan to amend the GL JS geocoder example to demonstrate how this can be done.
