status_detail->status unknown on invalid perfdata

Previously if viewing status detail for service with invalid perfdata
you would see a behavior where invalid critical threshold would always show the
test as critical.

New behavior (requires latest pynag) now turns the perfdata metric into unknown
if there is any invalid or unparsable input.

Fixes #166
