Shesh. The previous commit was a little premature. Drag the 

"GO" code in again, but only activate it when programming an
Xmega device through PDI.

Wonderfully consistent tools.

* jtagmkII.c (jtagmkII_close): The GO command before signing off
turned out to do more harm than good; on the Xmega, it caused exactly
the opposite reaction, the CPU stopped. Even without it, after the
RESET command, the target is running already. So, drop the GO.
turned out to be not required for normal megaAVR devices, and to
cause the exact opposite (i.e. the target stopping) on Xmega
devices being programmed to JTAG. However, programming Xmega
devcies through PDI *does* need the GO command.
