Represent "user must provide permission" in the schema about browser-compat-data

[Elchi3]

I think this would be an optional property in simple_support_statement:

"simple_support_statement": {
  "type": "object",
  "properties": {
    "prefix": { "type": "string" },
    "alternative_name": { "type": "string" },
    "flag": ...,
    "partial_implementation": { "type": "boolean" },
    "user_permission_required: { "type": "boolean" },
    ...
  }
},

Does user_permission_required sound good to you? Is this a boolean type or something else?

Boolean is good, additional information can be provided in the notes if necessary.

Maybe just permission_required? FxOS has some features that the OS only granted permissions to if the developer was trusted. If those cases show up again we could use the same property for those (though, maybe we do not want to do that in which case user_permission_required is good.

See the discussion in #190.
tl;dr we are not adding a new user_permission_required property and sub features should be used if the user permission was required at a later point than the basic support of the API.
