[SeaBIOS] Next release

[Kevin O'Connor]

I think it is time to start planning the next SeaBIOS release.  I'm
thinking of targeting a release around the end of January, with a
feature freeze in mid-January.

I'm thinking of calling the next release v1.8.  In previous releases,
three numbers were used (eg, v1.7.6), but there does not appear to be
a compelling reason to use more than two numbers (eg, v1.8) and the
two number approach is more similar to other projects (eg, QEMU and
Linux).

I'm not planning on pushing out the conversion to full 32bit only
drivers in the next release.  I maintain a branch with that code at:
  https://github.com/KevinOConnor/seabios/tree/testing-32bit-drivers
Such a change would potentially have backwards compatibility issues,
and I think it would be better to push a release with the current
enhancements (eg, the USB updates) first.

Thoughts?
