Test more dates in the past and future

There is now a Perl script that'll generate tests and result files to a wide variety of dates. From this we currently don't support < 1 AD or > 9999 AD. run_regressions is modified to remove the UNTIL option as I want to use a character after the test number to allow "subtests".
