SNES experimenting, debugging (reliable) comm.
SNES: More Experiments, code size / RAM tweaks
FODND reliable transport improvements for SNES
Contiki ext radio now uses unicast_send().

This enables the utilization of link-layer acks and thus much
more reliable unicast transfer in the presence of sleep scheduling MAC layers
such as ContikiMAC
Debug removal
SNES: plotting
all-collecting query
SNES plotting, switchable queries
