Embed-Codes lack proper attribution

[stkdiretto]

I was made aware by an OSM contributor that an embedded Transport map was lacking the proper attribution (“© OpenStreetMap contributors”) and only showed the “Tiles courtesy of Andy Allan” notice in the lower right corner.

As it turns out, the error appears to lie within the official embedding code I pulled from the official OSM site. The large map view shows the proper attribution, but the embedded IFrame doesn't.

Since I assume OSM is supposed to make re-using the maps as user-friendly as possible, I'd wager the attribution should be part of the embedded version, too, without requiring users to tweak it as to properly display the attribution information ;)

The embedded maps just use the default attributions from https://github.com/jfirebaugh/leaflet-osm/blob/master/leaflet-osm.js so any fix needs to be applied there - the large map has local customisations.

Looks like this was fixed upstream in openstreetmap/leaflet-osm@ef00c02 and we need to update our copy.
