Fixed issue where button coordinates were incorrect at `0` and `180` degree rotations. Added checks to prevent use of non-existent coordinates for NeoPixels.

For PyPI:
- Added `setup.py`
- Added PyPI release info to `.travis.yml`
- Updated `requirements.txt`
- Added a more comprehensive `.gitignore`
- Updated `README` with PyPI install instructions
