New Features
- removestar now works correctly with recursive star imports. In particular,
`from .submod import *` now works when submod is a submodule whose
`__init__.py` itself uses `import *` (removestar still skips `__init__.py`
files by default).
- `__all__` is now respected.
- The full path to the file is printed for `--verbose` messages.
- Catch all errors when importing external modules dynamically.
- Better error message for same-module absolute imports that don't exist.
Bug Fixes
- Don't consider `__builtins__` to be imported from external modules (even
though it technically is).
- Make sure pytest-doctestplus is installed when running the tests.
Other
- Include the LICENSE file in the distribution and the setup.py metadata.
