Fleet Commander Profile Format

This is a prototype for the default JSON profile format:

{
    "uid": "50M35TUP1DU1D",
    "name": "foobar",
    "description": "bleh",
    "settings": {
        "org.gnome.gsettings": [
            {
                "key": "/foo/bar",
                "schema": "org.gnome.terminal",
                "value": false,
            }
        ],
    },
}
