Initial port to the bitbox.

Uses the conio driver with a few tweaks to look a little less ugly.
Still not as good as the VNC one, but we don't have a 4 color textmode
(yet?). Some more custom chars and palette efforts like in the VNC
driver could make it look better, still.

TODO
- Embed more apps (but most of them are network related)
- Mouse support (USB)
- Network support (ENC28J60 or other)
- Filesystem on SD card + add the "directory" app
- Dynamic loader is not really needed, we can easily fit all apps in
  flash (more easily than in RAM, actually).
