ADTPro - feature complete beta released

[schmidtd <schmidtd@my-deja.com>]

I'm aiming for a "real" release of ADTPro on it's first birthday next
month.  Today's release represents the set of features I originally
set out to create (plus quite a few others along the way, but you know
how these things go).  Help me find the remaining bugs if you would,
please.

The last holdout was bare-metal bootstrapping all the way into ProDOS
with no DOS 3.3 in between.  I got that nailed down, so now I'm
done. :-)  Never booted ProDOS over the cassette port before?  Try it,
it's fun.

New functionality:

    * Bootstrapping from bare metal directly to ProDOS

    * Made serial bootstrapping pacing and speed
      configurable - making much higher baud rates
      possible (and reliable)

    * Included a ProDOS disk formatting utility (because
      you don't have any formatted disks yet, remember?)

    * Saving any 140k disk at the host always creates DOS
      order images; this increases compatibility with older
      emulators that don't understand ProDOS order images

Bug fixes:

    * Better recovery from ethernet initialization when there's
      no Uthernet card in the default slot

    * Cosmetic right-justification issue with online volume
      block number display (extant since 0.1.1)
