Feature Request: Support required array, vs required on each property

[tylerprete]

In json_schema v4, the idiomatic way to do required properties is with a required array at the end of the object:

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "$ref": "#/definitions/abc",
  "id": "resource:///json_schema/match/abc.json#",
  "definitions": {
    "abc": {
      "type": "object",
      "properties": {
        "name": {
          "type": "string"
        },
        "age": {
          "type": "string"
        }
      },
      "required": ["name", "age"]
    }
  }
}

jsonschema2pojo supports required on each property, but ignores the required array at the end.

We have a lot of files using this, so we don't really want to refactor them all. I'd be happy to try my hand at it, especially if you could point me in the right direction.
