This version has fake emeter and microcat drivers that just send a canned reply.
The environmental sensor drivers are unchanged. This version was made to test the
deployment system long term; A previous test, run with all drivers as-deployed, 
failed overnight. The SA showed a number of unprocessed messages, but appeared to be
hung up (we were unable to communicate with it without rebooting). The SK appeared
to still be running; we 'stole' the ethernet cable and sent a gettime command from
the testbed...SK responded OK to that. This code is designed to allow us to poll
at a very high rate, to hopefully expose the problem earlier. The failed test was
run with SA polling every 10 seconds. Using this code, we are polling every 5 seconds.
The failed test ran for at least 4 hours before the failure occurred.
