add jar files to Babel-17 project; package Babel-17 program

[phlegmaticprogrammer]

There should be a way to add jar files to Babel-17 projects, so that the native interface can access them; there should also be a way to package a Babel-17 program together with all jar files into a jar file that can be executed.

You can specify in the Netbeans Plugin now which additional jar files should be loaded
