RegisterInterface gradle build support

I have created a Java lib project that contains a slightly modified version of the RegisterInterface.java class. The lib is bundled up with appropriate jssc dependencies and is published to jitpack. The project is located at https://github.com/chuckb/RegisterInterface and the jitpack repo reference is located at https://jitpack.io/#com.chuckstechtalk/RegisterInterface

You should be able to simply add to your gradle.build file as instructed and do a gradle run. Jssc should come down automatically.
