v2017-09-10: Per booking maximum

Version 2017-09-10 introduces the ability to set per booking maximum limits for your experiences. This is useful if you want individuals booking for large groups to get in touch with you. The Xola checkout app will show the following message if the guest exceeds this limit: "Please contact us at <phone> or <email> if you are interested in booking a group larger than <orderMax>".

This change does introduce a change to the data structure of experience.group.

{
  "group": {
    "orderMin": 1,
    "orderMax": 6,  // new setting
    "outingMin": 4,
    "outingMax": 8, // formerly "group.max"
    "outingMinCutoff": 0
  }
}

{
  "group": {
    "min": 1,
    "max": 8,
    "outingMin": 4,
    "outingMinCutoff": 0
  }
}
