Metis boot loader

I now have some code to work with the Metis boot loader to allow you to read the MAC address, read and write the IP address and erase and program the FPGA flash memory.

It has been written using Qt 4 and uses the libpcap library for the raw ethernet interface. I have compiled and tested on Linux and Max OS X. It should also work on Windows.

This is intended as a disaster recovery method of reprogramming the FPGA on Metis.
