Prosperity 3.0.0-pre.1 bringing Prosperity up to par with Parity

I’ve begun redrafting License Zero’s noncommercial-license option, the Prosperity Public License, to mirror recent style and substance improvements to Parity 7.

Prosperity 3 can also build on cutting-edge work on noncommercial terms in Polyform Project’s Noncommercial and Free Trial terms.

As always, work continues in the GitHub repo.
