Bug#471927: [Scratch] Scratch 1.4 source code released under GPL v2

[Miriam Ruiz <miriam@debian.org>]

I've just found out something that might be a problem:

Scratch Support materials (/Help), sample Media files (/Media), and
sample projects (/Projects), are licensed under the Creative Commons
Attribution-ShareAlike 2.0 Generic (CC BY-SA 2.0) license. To view a

California, 94041, USA.

While Debian recognizes as DFSG-free CC BY-SA 3.0, there were AFAIK
issues with the version 2.0 of the license that were considered not
DFSG-free. Would there be any possibility of relicensing this stuff as
CC BY-SA 3.0 instead of the current 2.0 version?

Greetings and thanks,
Miry

PS: I'll keep working on the latest VM issues meanwhile.
