        Resets the dynamic objects in the sys module that the py and ipy consoles fight over.
        When a Python console starts it adopts certain display settings if they've already been set.
        If an ipy console has previously been run, then py uses its settings and ends up looking
        like an ipy console in terms of prompt and exception text. This method forces the Python
        console to create its own display settings since they won't exist.

        IPython does not have this problem since it always overwrites the display settings when it
        is run. Therefore this method only needs to be called before creating a Python console.
