- Use `from_id`, the changed field name in `PSMessage`.
- PR feedbacks
- Add label `test` in `testenv` in tox.ini, to avoid wrong
dispatching an environment's command in the future.
- Use `pytest` over `py.test`.
Previously, only the top level `libp2p` is included.
This left only `__init__.py` in the built distribution.
Use `setuptools.find_packages` with `exclude` instead, to avoid tiringly
list all of the subpackages.
