Add tox support for stem

Diff for getting tox support for stem. It will run everything over all python versions we want to support. This will also make it easier to get jenkins to run multiple python versions.

Note: There is a bug where the run_tests.py script does not return the proper error code(?) for tox, so it will complain about not being able to execute the given command if there are errors. This should be easy to solve tho.
