Add CL arg support to sidechain manipulation script
- Add support for command line arguments to the sidechain manipulation script. argparse requires Python 2.7 or 3.2+. - Add support for unlocking mainchain wallet when running send-to-sidechain. - Add various bits of help text, some of which may not be quite right.
