[feature request] Override Notification

[Jeff Weisberg]

| It'd be nice to have a config key that would make argus notify me when
| someone puts an object in override.

but the whole point of an override is to prevent getting notified.


but, when an override is installed something will be sent to
your 'notify_audit' 

and, you can add code that runs when an override is installed
by defining an 'override_policy' method and loading it with a
	load_modules: my_custom_code.pl

grep the source for 'override_policy', for details.
