Changeset 94

Message:

Added print decimal function to video module [v1.1.1-testing]

We don't need it yet, so it is disabled with 'IF 0'.
TODO: Better integrate Video and Aux output.

CAUTION:
This is a testbuild !
AirBoot uses the BIOS to access disks and a small coding error can trash
partition tables or other vital disk structures. You are advised to make
backups of TRACK0 and EBRs before using this testbuild. More info at:
