[ENSCORESW-478] and [ENSCORESW-467]. Brought in a Perl::Critic test being run on the lowest level. Tests are only run when we have the ENV TEST_AUTHOR is set to a true value. Otherwise it does not impact on the current test cases. Also had to fix a number of issues associcated with these flags. Mostly were due to not using warnings or strict. Anything I felt was ok or not my call has been annotated with a no critic flag.
