Bug Description

Reported by FaisaL Ahmed, http://www.faisalahmed.me/

In Mahara, changing the password doesn't destroys the other sessions which are
logged in with old passwords.
As other sessions is not destroyed, attacker may be still logged in your
account even after changing password, as his session is still
active.. he'll have complete access on your account till that session
So, your account remains insecure even after the changing of password.

We have 2 options to solve
1. Delete all active sessions right after an user changes his/her password
2. Facebook solved this issue by adding a process that asks
users whether user want to close all open sessions or not right after
changing password.

We should just delete all the users' other sessions, no need to ask them about it. Mahara doesn't have a "remember me" option like Facebook, so most of the time when you open your browser and navigate to a Mahara site you have to enter your password again anyway.

Dropping the priority to medium, because this is not an active vulnerability, but more of a defense-in-depth thing.

The user session also need to be destroyed when his/her account is deleted
