[RFC] Flapping-notifications (mis)feature

A couple of our customers have complained about Nagios sending 
notifications for hosts and services when a host is in scheduled 
downtime. Since scheduled downtime usually means "we're upgrading it and 
then testing the upgrade", this usually means each and every service on 
the machine will be sending a couple of notifications, often along with 
notifications for the host itself.

Going through the source, I see this is the intended behaviour

	$ grep -A 12 'SPECIAL CASE FOR FLAPPING' base/notifications.c

to see what I mean. I'm wondering about the usability of this. One good 
solution is to simply remove the "return OK" after the check for enabled 
flapping-notifications. Another, imo less good, is to move the entire 
block of code to below the "normal" case.

I thought I'd better check with people here to see how they feel about 
not getting flapping notifications for hosts and services in scheduled 
downtime before submitting a patch. I'm also a bit unsure if this 
belongs in the 3.x beta branch or if it's to be considered a bugfix and 
thus to be incorporated in the 2.x branch.
