Patch #100873 - Use registry to find proxies for urllib on Win32

Note that this patch looks worse than it is - an existing function (getproxies() for all platforms other than Win/Mac) has been moved, renamed and indentation changed, but the body of that function is identical.  Windows now allows the environment variables to override the registry.
