com2w: added some recovery code, improved protocol.
...
after sending a byte wait for the same time when sending the last bit as
with the other bits (otherwise the last bit might get lost by slower
devices).

avr: improved timing for sending bytes via com2w interface.
...
Still quite different among devices but that's just prove that the protocol
works without prior synchronisation.

avr: started working on new SPI-like COM protocol.
...
use a clock and a data line to introduce synchronisation into the
protocol to be able to work with the wide range of mcu speeds (no need for
exact timing, no need for exact calibration).
