basic plugin loading working, although going to have to switch to importlib instead. thats next
Ha, figured out importlib for what I needed, also got around missing API in pypy3.2 stdlib
removed unused streamlogging, it was unused. come back to it later if/when we need it.
ok, reworked code and now dbg/cmdline.py "sucessfully" runs its little tests.

removed lib/thread2.py due to py3+ no longer supporting the func needed (it was a dirty hack anyways. I should have learned a better way. now I did...)
