Create versioned releases

[mscottford]

It can be difficult to determine if specific changes are included in the executable that someone has installed. To help with that difficulty, we need to add versions.

Versions should be incremented each time the main branch is updated. A matching Git tag should be created each time a version is created. The dependency-history-maven repository provides a good example of this in action. Note that dependency-history-maven is being deployed to Maven Central, but we don't want to publish this program there.
