PUT and DELETE requests not supported

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start proxy
2. Make an HTTP PUT or DELETE request through proxy

What is the expected output? What do you see instead?

Expected proxying as with POST. Got the following error:

'r' referenced before assignment

The error occurs because `getMethod` does not account for these HTTP verbs 
(presumably because PUT and DELETE need more code):

    def getMethod(self):
        m = self.method.lower()
        if   m == "get":     r = HTTPRequest.METHOD_GET
        elif m == "post":    r = HTTPRequest.METHOD_POST
        elif m == "head":    r = HTTPRequest.METHOD_HEAD
        elif m == "options": r = HTTPRequest.METHOD_OPTIONS
        elif m == "connect": r = HTTPRequest.METHOD_CONNECT
    elif m == "unknown": r = HTTPRequest.METHOD_UNKNOWN
        return r
