Title: Cancel user attendance

Now it's possible to cancel your attendance (#5) by clicking Cancel Attendance button (Same as Signup with Github).

**To improve even more:**
I didn't find a good way to check if the user is already signed in with Github every page ready, so, if a user is already signed in with GH and is also attending to a meeting, the button will shows "Signup With GH".
