[Bf-committers] GPLv3 Released (for license gurus).

[Campbell Barton]

* how much of our code if any has the 'or later' clause?
* do we care about 'tivoization'?
* is there anything regarding software patent deals that effects us?
* what projects does blender use that v2/3 conflicts might happen?

I get the impression the extra stuff in this license wont effect blender 
much, more an issue of mixing the source code with other projects.

Personally Im happy to stick with v2 and see no advantage in changing.
But if the consensus was that there was an advantage in changing to 
share code with other projects (like moonlight3d) Id be okay about 
moving to v3 also.
