edusoho 支持同一账号多人同时登录

文件：

./src/Topxia/WebBundle/Listener/UserLoginTokenListener.php

函数：

public function onGetUserLoginListener(GetResponseEvent $event)

注释掉代码：

        if ($userLoginToken != $user['loginSessionId']) {
            $request->getSession()->invalidate();
            $this->container->get("security.context")->setToken(null);

            $goto = $this->container->get('router')->generate('login');

            $response = new RedirectResponse($goto, '302');
            setcookie("REMEMBERME", '', -1);
            $this->container->get('session')->getFlashBag()->add('danger', '此帐号已在别处登录，请重新登录');

            $event->setResponse($response);
        }
