GenJar JAR utility

In neverending pursuit to make our code faster, more eye-candy and, well, less bloated, I stumbled upon utility called GenJar. It is supposed to help build JAR files that contain only the needed classes - what it does is scans the class directory for root class(es) (provided in config file) and builds JAR with other classes that are needed by those root class to work. Very nifty, I was able to reduce the size of GMTI Generator's distribution JAR by 30% but it is not working good when it comes to SSR and SALT plugins, at least not with my configuration (I need to figure out what exactly is going on when plugin's classes are loaded).
