Require a license statement, and embed it in the JSON

[nicolas-raoul]

Having a license lets people fork decks without worrying about legal trouble. In case of share-alike licenses like CC-BY-SA or GNU-GPL, the license also prevents people from selling a derived deck without publishing it freely too. So, better require everyone to specify a license, and embed this license in the JSON file. The license question could be a very simple question when exporting:

- Should people who modify this deck make their modifications available to everyone? -> CC-BY-SA-3.0
- Can people do what they want with this deck, including selling a modified version of it? -> MIT
- Nobody is allowed to modify this deck? -> EULA

or something similar.

I dont think requiring people to specify a license (or setting a default one) is the way to go. The default "no license" would simply mean that noone except the publisher has any rights to the content, which is a sane default and should be kept as is.
