PGF web service: Return additional completion info with 'full' flag

BETA! The 'complete' command now has a new flag 'full' which when set
returns additional info about completions.

Without 'full' flag (default):

[
    {
        "from": "PhrasebookEng",
        "brackets": {
            "cat": "_",
            "fid": 0,
            "index": 0,
            "fun": "_",
            "children": [
                {
                    "token": "the"
                }
            ]
        },
        "text": "su",
        "completions": [
            "supermarket",
            "suspect"
        ]
    }
]

With full=true or full=yes:

[
    {
        "from": "PhrasebookEng",
        "brackets": {
            "cat": "_",
            "fid": 0,
            "index": 0,
            "fun": "_",
            "children": [
                {
                    "token": "the"
                }
            ]
        },
        "text": "su",
        "completions": [
            {
                "token": "supermarket",
                "funs": [
                    {
                        "fid": 421,
                        "fun": "Supermarket",
                        "hyps": [],
                        "cat": "PlaceKind"
                    }
                ]
            },
            {
                "token": "suspect",
                "funs": [
                    {
                        "fid": 445,
                        "fun": "Suspect",
                        "hyps": [],
                        "cat": "Property"
                    }
                ]
            }
        ]
    }
]
