FF: JSON data should be correctly formated

[oyeaussie]

If we are passing JSON data into FF, it should be re-written correctly. Example:

{
    "id": 42,
    "menu": "{\"home\":{\"title\":\"home\",\"icon\":\"home\",\"link\":\"home\",\"seq\":\"0\"}}",
    "apps": "{\"2\":{\"enabled\":true},\"3\":{\"enabled\":true},\"4\":{\"enabled\":true},\"5\":{\"enabled\":false}}",
    "app_type": "fintech",
    "route": "home",
    "sequence": 0
}

The above menu and apps should not have escape quotes. They should be re-written while save to avoid this.
