Use getopt for option parsing

[Gnewt]

Seems like options are parsed with some homegrown code. Using the existing getopt library would be more effective and easier. Is there any reason why it's not being used?

I would love to have the option parsing code cleaned up. That is pretty far down on my TODO list when compared to adding functionality. I would be very excited to see a pull request ;)
