Failed attempt at rfc2817 CONNECT method port forwarding
Attempt at using WrappingFactory to switch server to tcp port forward
Remove multiple inheritance and replace proxy classes

This is a big cleanup... however it still doesn't work =-|
Add more log messages
Add HTTP 200 response to CONNECT method processing

Duh! I finally read the RFC 2817 section 5.3 Establishing a Tunnel with CONNECT:

"""
   Any successful (2xx) response to a CONNECT request indicates that the
   proxy has established a connection to the requested host and port,
   and has switched to tunneling the current connection to that server
   connection.
"""
Remove ShinyProxyClient and ProtocolSwitcherWrappingFactory

Here we also clean up the logging and docstrings
