Replacement boot loader - "CoLo"

I'm currently working on a new boot loader for the Microservers that overcomes some of the limitations in the original loader. It can boot from disk or over a network via TFTP or NFS and DHCP.

Please read the warnings in the documentation before erasing/over-programming the original Cobalt boot loader
