License under Creative Commons BY-SA 3.0

This is a follow-up from my comment here: #1079 (comment)

My interpretation is that the Scala Code of Conduct builds on the Citizen Code of Conduct, at least implicitly by referencing it. Since the Citizen CoC uses this license, it requires that derived works use the same license. This will cascade to other derivatives of the Scala CoC.

I don't want to argue for or against the merits of this license, or its appropriateness for this purpose. I have no strong personal opinion on that. The main question is whether the Scala CoC is obligated to adopt it by being derived from Citizen CoC.

I'd say it's a grey area in the Scala CoC as currently written, whether it would be considered a derived work. With the inlining of text from Citizen CoC in #1079, it would be clearly required to adopt the BY-SA 3.0 license (or a compatible one). So, if this change isn't accepted, I'll revert that change in #1079.

even apart from the question of whether we're obligated, it seems like a desirable change to me regardless! desirable to be explicit about the license status of the code's text. and BY-SA seems like the appropriate choice

@sjrd @darjutak wdyt?

@sjrd @darjutak @heathermiller are you OK to merge this?

[SethTisue]

This has been pending a long time now, so I'm going to go ahead and hit "merge", since no one has raised any concerns about it.
