1.12 Branching complete

[Matthew Dillon]

    1.12 has been branched!  I've done a rough nrelease build with HEAD
    but haven't tested that a nrelease build with 1.12 produces the correct
    version information yet.  Other then that it went pretty smoothly.

    There were no installer issues once I completely regenerated the
    binary packages.  I have updated the nrelease Makefile to use the
    new binary packages (including a completely new bootstrap), for fresh
    installs.
