Allow a subset of tests to fail

When a bug is found, often the hardest part is replicating the behavior. If that failure can be replicated, it should be codified in a test. However, that test will not pass until the bug is fixed. As such, we will provide a decorator for the test that will skip it under normal circumstances. When an additional switch it set, the test will run to failure. A Report will then show the set of failing tests compared to passing tests. When a bug is fixed, the decorator will be removed from the failing test.
