#174 xmlstatus: won't work with multiple checknames or multiple hostnames

[Ulrich Herbst]

In xmlstatus is currently a (bad) workaround to fix this issue.
But: that's an issue with the complete agent handling, not just with xmlstatus check:

If there are multiple <XMLSTATUS>-instances defined with different hostnames and / or different checknames, that should be outputed, too. But that's not the case.

Todos:
- Generate testcase
- Fix it.
