When patching, Getdown will move foo.jar to foo.jar.old and then patch that file to create a new foo.jar. That results in foo.jar.old being passed into JarDiffPatcher as the source file, which it then inspects to determine whether it is a zip file or a jar file based on its file extension. Since that file extension has already changed to .xxx.old, we need to handle that. Closes #230.
