Make Herd work from any path
Added argparse options instead of raw sys argv, fixed a regex bug where it wasn't acurately snagging comments, added in a retry option in case murder fails becaues of a time out or other problem.

Additionally, patched murder_client to return 1 in case of failure or error so that it can be handled upstream (It was returning success in all situations).
