Add a macro to the SPI library that reads activity from a bus and prints it to 
the
terminal until stopped with escape.

Macro added, setup and teardown functions added. For some reason it doesn't 
work yet
(probably setup value).

Fixed pin assignment problem. Bus sniffer works. According to errata, CS filter
doesn't work in rev 3 silicon. Workaround is to watch (poll) the PORT pin and 
wait
for correct CS direction change (this also allows directional configuration). 

Need to add: 
CS filter routine,
Configurable CS edge select,
resync command for no filter mode (?)

Added configurable edge select and detect. No resync command (later?)

Need to put second SPI hardware module on the MOSI pin so it snoopes data in 
both
directions.
