Include all files in the PyPI releases

- Included tests, examples, etc in MANIFEST.in.
- Made git ignore files that should not be included in the package.
- Added tox test environment which runs check-manifest to validate the
  MANIFEST.in file.

Downstreams like Debian prefer the PyPI packages to include everything
from the Git repo, especially changelogs and test suites. To make the
installation with pip as lightweight as possible, it is encouraged to
build and upload Python wheels in addition to the sdist tarball.
