loginDialog: On login, allow logout a conflicting session
When opening a session, find if there's already a session opened for the
same user with the help of Loginmanager.
When it's found, display the conflicting session dialog.
The logout dialog allows shutting down the conflicting session using the
greeter dbus method "StopConflictingSession".
If the dialog is already opened and the conflicting session has been
closed on its side, the new session will start.
