Check_MK Werk 8070: Fix notification type for the end of downtimes

ID: 8070 Title: Fix notification type for the end of downtimes Component: cmc Level: 2 Class: Bug fix Version: 1.2.5i6 When a downtime ends the CMC used to set the NOTIFICATION_TYPE to <tt>DOWNTIMESTOPPED</tt>, while Nagios uses <tt>DOWNTIMEEND</tt>. This leads to an invalid notification classification in the rule based notification, so that instead of the type <i>Downtime Start or End</i> a normal altert type was being assumed. That has been fixed now.
