- Move option parsing utiliities to proxy.py
- Don't have a global config object. Pass it as an argument to ProxyServer.
- Simplify certificate generation logic.
- Use templates for config files. We can re-introduce customization of the
certificate attributes when we need them.
- Split CA and cert generation into separate functions.
- Generation methods provide an error return when generation fails.
- When the user explicitly specifies a certificate, we don't generate it, but
fail if it doesn't exist.
Also, since BeautifulSoup is so damn slow, print a statusbar message saying
that we're calculating a pretty version of the response. Maybe I should add
hangman or something, becuase on a 200k document this can take ages.
