Query Status and Shutdown Daemon

This release gives the ability to do a simple heartbeat check over the port defined by network.local.port. The python script python/status_send.py tests this. By sending the string "STAT" to the port, the daemon will return OK if alive.

Also, the same port can be used to shut down the daemon. The python script python/send_quit.py tests this. By sending the string "QUIT" to the port, the daemon will return "QT" and shutdown.
