Make parsenvy importable with import parsenvy

This commit changes parsenvy importing from `from parsenvy import
parsenvy` to `import parsenvy`.

This entails:
- Updating __init__.py to import everything
- Updating setup.py for PyPI's sake
- Updating tests
- Updating the README
- Updating the CHANGELOG (is this supposed to be in commit messages?)
