Add Automatic-Module-Name (for Java libs)

[hendrikebbers]

The java modules does have a module-info.java or provide an "Automatic-Module-Name" (in MANIFEST.MF). At least the info to the manifest should be added to provide compatibility in projects that use the Java module system. More details: http://branchandbound.net/blog/java/2017/12/automatic-module-name/
For this project as a first simple step a MVN plugin would be good enough to add "Automatic-Module-Name" to all modules. If you are interested I could create a PR the next days :)

@hendrikebbers - please go for it. One minor warning is that this project compiles in JDK8. Not sure if the maven stuff will do what want in that version, but feel free to give it a shot.

@ashleyfrieze the simplest solution is to add metadata to the MANIFEST. That is independent of the Java version. I will start with that step.

@hendrikebbers - sounds great. Give me a shout if you need help.

Long-term I will stop supporting JDK8, or at least branch that off and focus more on later Java versions. For now, if you're able to get things building using the mvnw and a JDK 8 environment, that'll be great.

Note: this software will not build on later Java versions.
