Release notes in the Wiki & downloads page

Hi all,

I’m happy to see that SDL 2.0.2 is going to be released and that it’ll
carry improved Android joystick support!

I would like to make a suggestion: maybe it’d be a good idea to keep the
release notes in the Wiki for all the releases (since SDL 2.0.0) and a copy
of each release’s notes linked in its associated download page, just for
reference.

Of course they’re available in the source code, but it’d be convenient to
have them in the other places, too.

Kind regards,
Joseba
