Added source and cid to e1.31 driver. (#207) 

source defaults to "hyperion on <hostname>"
cid defautls to randomly generated on each startup

        "device" :
        {
                "name"       : "DMX_e131",
                "type"       : "e131",
                "universe"   : 1,
                "cid" : "{204b83c-efb5-4b23-b2d0-35939d561061}",
                "source-name": "This is my custom e1.31 source",
                "host"       : "239.255.0.1",
                "port"       : 5568,
                "colorOrder" : "rgb"
        },
