- Removed unnecessary imports.
- Reorganized import order.
- Removed legacy import conditions.
- Added python3 shebang to pesterchum.py
- Set QString to always be str, Python 2 is not supported.
- Depreciated luaquirks.
- Added ValueError to write exception block
- Set "pynotify" to always be none, even if pynotify succesfully imported, since pynotify implementation is broken.
