Move the code that copies the dylib's to the bundle to a new script (dylib-unhell.py) which is called by osxbundle.py. dylib-unhell is about 20x faster than the previous implementation. This is accomplished by removing superflous shell-out operations which are kept track of using an in memory tree of all the needed dependencies. Moreover the shell-outs have been further optimized by not requiring a complete shell for every operation and just using subprocess.call (which is equivalent to Popen).
