Universal PCB update

I've wired the first Universal PCB I made as a stepper controller, modified the driver software so it will work both this and the old design, and fired it up with a little ex-HP-printer stepper connected as a test - seems to work.

In the University tomorrow Ed and I'll put it in ARNIE and see how hot the L298N gets (the 754410 gets jolly hot...).

It's always a good idea to bolt a heat sink on the L298N. It will save you burning off a fingerprint, like I did. :-)
