Pq test harness usability and error reporting improvements.

Pq script errors are now printed in test output in case they are being masked by a later error.

Once a script error occurs, the same error will be thrown forever rather than throwing a new error on the next item in the script.

HRNPQ_MACRO_CLOSE() is not required in scripts unless harnessPqScriptStrictSet(true) is called.  Most higher-level tests should not need to run in strict mode.

The command/check test seems to require strict mode but there's no apparent reason why it should.  This would be a good thing to look into at some point.
