Empty host/service-group patch

Hi all,

a small patch that stomps down a bug in parsing
empty host/service-groups.

strtok is fed a NULL value for the members in an
empty host/service-group. Instead of initiating
a new string value, strtok continues were it left
of with its previous non-NULL value and returns
true bogus crap.

In rare occations this resuts in a "zombie" host/
service with a strange random name. I've been really
confused by configurations that pass the verification
(nagios -v ..), but fail on nagios startup. Nasty!

The attached patch makes sure that strtok is never
called with a NULL value for host/service group
members. Please include or comment.

Thanks in adv
/S-G
