Incorrect OSM license

[Marko Dimjašević]

In the OpenStreetMap plugin, there is the copyright statment of the OpenStreetMap license that reads CC-BY-SA. I believe that's wrong because it changed a year or two ago. Now the data is available under the Open Data Commons Open Database License (ODbL), but as it says at:

​http://www.openstreetmap.org/copyright

if using map tiles (which is the case in the plugin), the cartography is licensed as CC-BY-SA. As far as I got it, both information should be stated. For more details on copyright and attribution check the provided link.

TL;DR: I believe if we state CC_BY_SA and link to their copyright page, we are fine.

I have not seen the OpenStreetMap plugin in action yet, so excuse me if I am saying irrelevant stuff. This is from ​http://www.openstreetmap.org/copyright:

The cartography in our map tiles, and our documentation, are licensed under the
Creative Commons Attribution-ShareAlike 2.0 license (CC-BY-SA).

We require that you use the credit “© OpenStreetMap contributors”.

You must also make it clear that the data is available under the Open Database
License, and if using our map tiles, that the cartography is licensed as CC-BY-SA.
You may do this by linking to this copyright page. Alternatively, and as a
requirement if you are distributing OSM in a data form, you can name and link
directly to the license(s). ....

For a browsable electronic map, the credit should appear in the corner of the map.

Their example simply states "(c) OpenStreetMap contributors" with OpenStreetMap being a link to the above copyright page. So, I believe if we state CC_BY_SA and link to their copyright page, we are fine.

This would be taken care of with my proposed patch in issue 410

Fixed! Closed with #410

Fixup target version, so it's possibly easier to write release notes.
