Facilitate releases in node projects.

Extends git flow model. Requires that git flow is initialized with master and develop branches.

Creating a release does the following:

1. Updates the version of the project.
2. Creates a release/${version} branch, where ${version} is the updated version number.
3. Commits the version upgrade to the release.
4. Merges the branch into master and develop.
5. Tags master with ${version}
6. Pushes updated master and develop, and pushes new tag.
