support the start up delay time debug
revised the libs loading process, implemented the export function (copy files from the jar to the out side world), added the convenience to copy the Lib/sikuli folder containing the Jython API to the libs folder when running in plain Jython environments.
added jar utility functions: folder to jar (packJar), jar to folder (unpackJar) and buildJar to make a jar by combining other jars and folders (will be used by setup and later to make jars from more complex scripting structures)
