Return a test suite with all the tests from a module.

Included are TestCase subclasses and doctests listed in the module's __doctests__ module. If that's not good for you, put a function named either testSuite or test_suite in your module that returns a TestSuite, and I'll use the results of that instead.

If testSuite and test_suite are both present, then I'll use testSuite.
