Title: Fix for Abort Session notification

When user A aborts a secure session with user B, clear the keys
as before, then send a message to user B notifying them that
the secure session has been closed. Upon receiving the abort
session message, user B's keys will automatically be cleared
and they will be put back into an insecure state.

Fixes Issue #143
