[PATCH] Distinguish between warning and critical notifications

[Mark Gius]

Flap detection is to prevent rapid pages due to a service that 
constantly changes state.  So if a service is transitioning from WARNING 
to CRITICAL every minute, each time Nagios checks the state will have 
changed and it will send out a new notification to reflect that change.

I am hoping to avoid the issue where a service that is in WARNING for 
long enough will eventually page every person in the escalation chain.  
(see original email).
