Resolves #1: Installs and deploys should happen at end of builds.

This should really only affect multi-module builds.
The Maven release prepare & perform run did not commit version bumps.

Committing the end result here. Will push fixes and a new release to
resolve fully.
Bumping to the latest maven-release-plugin version.

This will hopefully fix the "POM wasn't committed during release"
problem that I just ran into. That problem may have been related to some
of these issues:
