Fundamentals in CC-BY

(Copy, Paste)

In the aftermath of the whole "We want backsies on the OGL" thing, it seemed good to put my things under CC-BY just to make the permission to use clearly irrevocable.  The original "unlicense" remains in place for any situation where use of CC-BY material  is unwieldy or problematic.

The same or very similar updates are being applied to my other material, though it'll be spread out over a few days.
