Subject: PGF Web Service: include entire completion in full mode

When using full=yes in the web service 'complete' command,
you now get an additional field 'seq' with the longest possible completion.
So, given:

  lin
    f1 = ss "the" ;
    f2 = ss ("the red house" | "the real deal") ;

and trying to complete on input "th", you get:

    [
        {
            "from": "TestCnc",
            "brackets": {
                "cat": "_",
                "fid": 0,
                "index": 0,
                "fun": "_",
                "children": []
            },
            "text": "th",
            "completions": [
                {
                    "token": "the",
                    "funs": [
                        {
                            "fun": "f1",
                            "hyps": [],
                            "cat": "C",
                            "seq": "the"
                        },
                        {
                            "fun": "f2",
                            "hyps": [],
                            "cat": "C",
                            "seq": "the red house"
                        },
                        {
                            "fun": "f2",
                            "hyps": [],
                            "cat": "C",
                            "seq": "the real deal"
                        }
                    ]
                }
            ]
        }
    ]
