Title: moved DummyMod to proper namespace to enable dill pickling

enables pickling with dill, which worked in 0.13, but seemed to be broken in 1.0.

Issues remain, however, since dill.dump_session now saves "DummyMod" stub and not the user's interactive session. Needs more investigation into reason behind DummyMod, and if it's really a necessary evil.
