TYPO3 Core

In a functional test I need to test Extbase controller which depends on Frontend user sessions. The current \TYPO3\CMS\Core\Tests\FunctionalTestCase::getFrontendResponse() doesn't allow me to pass cookies to the Frontend and \TYPO3\CMS\Core\Tests\Functional\Framework\Frontend\Response doesn't allow me to fetch cookies from the Frontend. My proposal would be:

class FunctionalTestCase {

  protected function getFrontendResponse($pageId, $languageId = 0, $backendUserId = 0, $workspaceId = 0, $failOnFailure = true, $frontendUserId = 0, array $cookies = array()) {
    [...]
  }
}

class Response {

  /**
   * @return array|NULL
   */
  public function getCookies() {
    [...]
  }
}

I've already implemented this by using xdebug_get_headers which would be a dependencies for this feature. So I could contribute if you want.
