Class proxy

This class defines a simple HTTP proxy, it is mainly used for "complex" plugins.

You should call it like this:
        ws = proxy( '127.0.0.1', 8080, urlOpener )
        ws.start2()

Or like this, if you want to override the proxyHandler (most times you want to do it...):
        ws = proxy( '127.0.0.1', 8080, urlOpener, proxyHandler=pH )
        ws.start2()

Where pH is a class like this:
        class w3afProxyHandler(BaseHTTPRequestHandler):
                def do_GET(self):
                        ...
                        ...
