Pillow now requires the olefile Python package through setup.py. This removes Pillow's maintenance of this library by instead relying on and reusing the upstream version. No longer need to regularly update the vendored package and docs. olefile bug fixes and features can go directly upstream. During travis tests, now installs Pillow package before tests; this will also install all dependencies (currently, only olefile).
