[MiNT] New branches !

[Alan Hourihane <alanh@fairlite.co.uk>]

Hello All,

You'll have probably noticed a lot of commit messages.

Odd has requested that I revert his changes and put them onto a branch
given that his work is not yet complete and the build is broken. I
didn't want to do this, but Odd asked, so I've done. Given this though,
there's some nice fixes on the new "ozk-enhancements" branch that is
worth poking through and systematically bringing to the mainline code.
I'll be starting on this asap.

Secondly, I've created a branch "helmut-enhancements" with Helmut's own
XAAES changes too.

Hopefully we'll be able to reconcile all these recent changes into the
mainline code along with my own "freemint-enhancements" branch as a
pre-cursor to a new release.

Alan.
