This allows us to have more complex test files where an action is taken, then
we test something, then another action is taken, etc.
Changes to test files are required so that URL is defined after all the
required settings are set.
Changes to the result files are either whitespace changes due to above logic
changes, or printing out a SQL Result header before each result. I figured it
was useful.
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".
