Add a way to configure the scope

[RKrahl]

For the moment, the scope of the dependencies is hard coded to module. That means that a test can only be marked as dependent on a test in the same module, but cannot depend on a test in a different module. The backend class DependencyManager is in principle also capable to work on session scope. But the calling hooks do not use the optional scope argument in the getManager() call.

The difficulty is that I have no idea how to define a clean API to configure the scope from the calling tests.

I think it does what you want, and is sane. All the existing tests still pass.
Let me know if you approve or want changes and I can add some documentation
