WIP.
(Cherry-pick from krall's branch)
Report class_setup, class_teardown, and class_setup_teardown runs.

Conflicts:

	testify/test_case.py
	testify/test_reporter.py
PoC where class_teardown failure marks tests in the TestyCase as failed.
This isn't right but I'm about to move this to a different file.
Move fixture exception test to test_logger_test.
todo
class_teardown exception info appends rather than clobbers.
Raise Exception if we encounter inconsistent error state in result object.
Notes
Refactor to create _run_tests().
A test for errors during class_setup.

Message
Extract TestReporterExceptionInClassFixtureSampleTests.
Extract _get_test_results. Start writing SQLReporterExceptionInClassFixtureTestCase before realizing that I should pin down the behavior in TextLogger first.
fix LetWithSubclassTest
add a broken test for issue 104
