Host RCs are now properly mapped, both in statusdat and livestatus

The mapping of host check results to the standard service check RCs
is per default now:

 Host                  check_multi
 -------------------------------------
 DOWN (RC 1)        -> CRITICAL (RC 2)
 UNREACHABLE (RC 2) -> UNKNOWN (RC 3)

You may use the following variables to force a different behaviour:
1. map_host_down_state_to=RC
2. map_host_unreachable_state_to=RC

Thanks again to Gerhard Lausser for the bug report.
