Warning / Critical break-out in Test

The requirements code computes the max of all requirement messages, which is great, but...

One might want to address the "critical" issues first, to get the red out.

This patch adds the Nagios status to each requirement text:

> $severity_nagios_text = array(
> REQUIREMENT_DEBUG => 'OK',
> REQUIREMENT_INFO => 'OK',
> REQUIREMENT_NOTICE => 'OK',
> REQUIREMENT_WARNING => 'WARNING',
> REQUIREMENT_ERROR => 'CRITICAL',
> REQUIREMENT_CRITICAL => 'CRITICAL',
> REQUIREMENT_ALERT => 'CRITICAL',
> REQUIREMENT_EMERG => 'CRITICAL',
> );
