Enable auto detection of proxy configuration

[snakefoot]

            IWebProxy proxy = WebRequest.GetSystemWebProxy();
            proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
            request.Proxy = proxy;
            request.PreAuthenticate = true;

Cache the default proxy to avoid auto lookup for every WebRequest.

Maybe a tristate (Explicit Proxy, Auto Proxy, Without Proxy - null):

Can also be configured globally for the entire application:

<system.net>
    <defaultProxy enabled="true" useDefaultCredentials="true">
         <proxy usesystemdefault="True" />
    </defaultProxy>
</system.net>
