Paylater buttons present and controlled
(LB-40) Support for force select list

LB asked for all elements to be select lists.  In the furture I would
like to see site specific ejs files but for now there is a temporary
switch allow it to ve force in the extras array:

    ￼"webExtras": [
    ￼{
        "code": "HIGH",
        "description": "Highchair",
        "type": "optional",
        "quantity": 2,
        "price": "11.00",
        "total": 11,
        "maxLimit": 2,
        "forceSelect": true
    },
    ...
