Automated the fat jar creation process.

- Added a modified version of JarSplice in the tools/ directory, which can run using system properties as well as the GUI.  The project is located here: https://github.com/itdelatrisu/JarSplicePlus
- To create a fat jar, execute the Maven goal "install -Djar".  The output file will be in the target/ directory and suffixed "-runnable".
