1 - After tapping an invitation notification, have to "wake up" ChatSecure to get Decline/Accept.
Have to go to another screen to get Decline/Accept.
2 - When deleting a contact, it doesn't actually get deleted. Stays on contact list, with offline indication.
It may go away when you Exit and go back, and it may go if you delete it a second or third time.
3 - Really need contact alias.
