ObjectStream has static format method on it. Device now publishes logs
to the proper pubsub topic

Added tests for device transitions log/pubsub. Bug in device. Logger
no longer appends unixtime to log obj going to pubsub
Added monitor link for logs on device
Links for adding remote device and monitor server logs use loader.path for proxy connections
Logger is publishing to proper topic. peer_client uses server's instance
of Logger if supplied
Monitor link on server uses ws://, logs use timestamp instead of date.
More fixes with formating stream objects
Logger no longer uses the bunyan hook when sending events to the pubsub.
