[AngularJS] Promises. 3. config().when() -- resolve: {doFisrt: ....., doSecond: ....}

//In the previous example, we show write a promise in the config funciton,
//But we can image if the logic get complex, the code would be ugly,
//there is a way to handle the code in config, it is using "resovle:{}"
