I removed these lines becuase if you invoke, say, ``./tests/acceptance/testall 02_classes/02_functions`` you'll always fail because the staging tests are always implicitly run.

Using the ``--staging`` option however let's you be explicit about your intentions. The new "test group" heading provides a visual, logged cue before that wtf moment when the tests you thought you were running get skipped :)

Even with these two lines removed, the default is to enable the Network tests; you'd need to pass ``--no-network`` to explicitly skip them.
