Title: Fixed the default value for the "required" flag of header-, cookie-, and form-parameters

According to the spec (https://github.com/wordnik/swagger-spec/blob/master/versions/2.0.md#parameterObject),
only "path" parameters are required by default, while for all other parameter types the default value for the "required" flag should be "false".
