introduce configurable error handlers and default error handler for application/vnd.error+json

[mvcatsifma]

Introduce a generic error handler for application/vnd.error+json, that publishes the error as an error object on the response:

Something along these lines:

factory('errorInterceptor', function ($q, HalError) {
  return {
    'responseError': function (response) {
      if (response.headers('Content-Type') === 'application/vnd.error+json') {
        response.error = new HalError(response.data);
      } else {
        response.error = {
          message: response.statusText,
          status: response.status
        };
      }
      return $q.reject(response);
    }
  };
})

Als introduce mechanism for client of the library to configure their own error handlers by media type.
