Checkable::GetSeverity(): always take reachability into account

Browse Source 
So far, Service::GetSeverity() only considered the state of its own host, i.e.
the implicit service to its own host dependency, and treated it similar to
acknowledgements and downtimes. In contrast, Host::GetSeverity() considered
reachability and treated it like a state, i.e. for the severity calculation,
the host was either up, down, or unreachable.

This commit changes the following things:
1. Make the service severity also consider explicitly configured dependencies
   by using IsReachable().
2. Prefer acknowledgements and downtimes over unreachability in the severity
   calculation so that if an already acknowledged or in-downtime services (i.e.
   already handled service) becomes unreachable, it shouln't become more
   severe.
3. To unify host and service severities a bit, hosts now use the same logic
   that treats reachability more like acknowledgements/downtimes instead of
   like a state (changing the other way around would the state from the check
   plugin would not affect the severity for unrachable services anymore).
