Clarified/fixed the SSL & debug related docs
The quickstart() server is production-ready and is preferred

I misunderstood that the quickstart() server is for production and just
needs to be configured with an environment to enable/disable debugging
options. It is also a WSGI server and is a better choice than the
stand-alone CherryPyWSGIServer for serving a CherryPy app because the
coupling is tighter and debugging output is not lost.
Added appropriate environment configuration for various deploy methods
