Added ability to communicate to the local Serial port using an IRC chat client

1) Launch the miniircd server
2) Launch your IRC client, point it to this server (e.g. localhost)
3) Open up a channel to your serial port (e.g. #/dev/tty.usbmodem14111)
4) Type in a message to your serial device

Limitations:
* Currently only supports 115200,N,8,1
* Haven’t tested this on Windows, only Mac
