* Method "list_tests" returns methods from own class and base classes.
* Method "tear_down" is called if "set_up" failed too.
* Code was slightly reformatted.
* New type of test status "failure" is set if the test unit fails.
* Old type of test status "error" is set if error was occured in "set_up" or
"tear_down" method.
* Error on "set_up" or "tear_down" doesn't stop whole test runner.
* Fix for tainted mode.
* Stringify eval error explicity in case that exception object doesn't
support "eq" operator.
* Does not use Symbol::stash sub.
