negate now has the ability to replace the status text as well (-s, --substitute)

Also changed:
 - default timeout to 11 instead of 9 (since it's recommended to have a higher timeout, and many plugins default to 10 seconds)
 - If there's no STDOUT lines returned, still returns the returned result if it's NON-ok instead of forcing it to UNKNOWN
