aastra 6735i CT model incorrect

[mariedling]

The section in aastra/aap9xxx6xxx/family_data.json should be:

  {
    "model": "6735i CT",
    "lines": "9",
    "id": "12",
    "template_data": [
      "template_data.json",
      "prgkeys.json",
      "softkeys.json",
      "featurekeys.json",
      "expmod1.json",
      "expmod2.json",
      "expmod3.json"
    ]
  },

As the phone does not have a topkeys.json section, but needs the prgkeys.json.
