pyswitch utility updated. Much more user friendly interface (better help, more options), and fully refactored code base.

Utility is much more user friendly than the first version, with increased functionality (use --help flag to see improvements).
As it stands however the utility is pretty computer-specific. Making it useful on a different machine would entail adjusting the code. Next step then is to explore ways to customise the utility via the command line.
