This removes parts of the nearly identical code from all monitors. The removal of monitor type specific event checking is done based on the assumption that only the monitor that is monitoring the server can be the cause for a state change. This removes the need to actually check that the state change is relevant for each monitor and allows the event handling to be moved into the core.
