write a release script

[chadwhitacre]

needs to change version in:

• setup.py
• docs/conf.py
• postgres/__init__.py

[chadwhitacre]

update $version
git commit -m "Bump version to $version"
git tag $version
add "-dev" to $version
git commit -m "Bump version to $version"
git push --tags

Also make a release in the GitHub UI, I guess:

https://github.com/gittip/postgres.py/releases/

[chadwhitacre]

git checkout $version
python setup.py sdist upload
