Password Changed Notification Email

Searched but didn't find this anywhere.
v1.5.6.1

Would be nice if upon password change an email is auto sent to user notifying them that password HAS been changed (just a measure of security for the user in case of possible account hacking....)

I'd like to see the system reworked so password changes are run through an email link. That way I can't (temporarily) lock you out of your account just by knowing your email address.
