Modifying specref's deliveredBy property.

Hi,

About to change specref's deliveredBy property from an array of strings to
an array of objects of the form { url: String, shortname: String }.

So for example:

        ["http://www.w3.org/2009/dap/", "http://www.w3.org/2011/04/webrtc/"]


will become:

        [
            {
                "url": "http://www.w3.org/2009/dap/",
                "shortname": "dap"
            },
            {
                "url": "http://www.w3.org/2011/04/webrtc/",
                "shortname": "webrtc"
            }
        ]

If this an issue for you, please ping me immediately.

Thanks,
