Openstreetmap function broken; easy fix

[gitsmol]

The --osm flag results in an error. This is because the osmviz library has deprecated OSMManager.createOSMImage in favor of OSMManager.create_osm_image.

Change line 702 to:
image, bounds = osm.create_osm_image((c1.lat, c2.lat, c1.lon, c2.lon),

and it is fixed.

Will be fixed by #62.
