Add per-testcase timestamps with an option to disable them

+You can use the --notimestamps command line option to turn off timestamps of
+individual testcases if you want a less verbose output (though test code may
+override this default by setting the testTimestamps variable itself).
+
 You can also use the --developer command line option to define the TESTDEV
 pre-processor variable (to turn on developer only test cases, and to have
 all 'hopes' treated as actual 'tests' with pass/fail results).
