Implement CI build/packaging for release

[ebresie]

This is to help automate the build of Netbeans module to help in installation. So it will build an nbm which can be downloaded and installed within Netbeans.

At some point some form of automated push to the plugin portal may be implemented or may use the artifact her to publish to the portal.
