[Live-demo] Natural Earth in 4.5b2

Brian and I have been chatting on IRC, and here are our suggestions:

We note that the current naturalearth dataset has topological errors 
which may be an issue for some of the applications on OSGeo-Live.
It will be good to have naturalearth's quality assurance process 
improved such that these errors are removed before they release, but I 
expect that will take time to put in place, and we want to lock down 
OSGeo-Live for this release.

I understand that Brian has been able to clean up the dataset. What I 
suggest is that we put this cleaned dataset on download.osgeo.org 
(keeping the same layer names), and bump the version number of the data. 
Eg: 1.3.1 or 1.3osgeolive1

By the time we are working on the osgeolive5.0 release, I hope that we 
can work with the naturalearth team to improve their QA process so that 
the naturalearth dataset is topologically correct.

Nathan, how does that sound to you?
