How to release pyd
- update version.txt (optional, should self correct if you forget)
- set a git tag in semver format (vX.Y.Z)
- that should take care of code.dlang.org
- deploy to pypi is through travis, so it should be automatic, but travis can get crapped up
- readthedocs apparently updates itself
- waa! wish we had a way to generate api docs!
