Properties generation look wrong

Any variation of properties like:

@:expose
class G {
    var _field: String;
    public var field(get, set): String;
    function get_field(): String { return null; }
    function set_field(value: String): String { return _field = value; }
}

are generated as:

export class G {
    private constructor();
    field: string;
}

Haxe doesn't normally generate native JS getters, so get_field/set_field should be exposed.
