* Bugfixes for building executable
This commit has several bug fixes.
- Add required python packages that were missing from setup.py
- Add hiddenimports for pyinstaller so that pyinstaller properly loads gevent
- Modify noxfile so that it loads the required packages when creating a session. Also, python 3.7 support was added in pyinstaller 3.4, so pyinstaller version needs to be updated.
