Java 9 modular support request

[andye2004]

As per title, are there any plans to support Java 9 module system?

What has to be done? Accepting PR for this...

A missing manifest entry inside the eventbus jar file causes the following warning on a build that uses the eventbus library and has the module system enabled.

[WARNING] ***********************************************************************************************************************************************
[WARNING] * Required filename-based automodules detected: [eventbus-java-3.3.1.jar]. Please don't publish this project to a public artifact repository! *
[WARNING] ***********************************************************************************************************************************************

The solution to this should be very simple. Just add the following lines to the build.gradle files of each eventbus jar module (eventbus-java, eventbus[-android])

jar {
    manifest {
        attributes("Automatic-Module-Name": "eventbus.java") // <- my suggestion: eventbus.java and eventbus.android respectively
    }
}

EDIT: I tested it on my local machine and it works perfectly fine.
