Easy Auto Proxy in C# using app.config

One of the feature requests that I got for the next version of RipShout was proxy support for people tuning in at work.  I didn’t want to bog the app (which I intended to be very slim) down with a config window and permanent storage.  As is often the case, the answer presented itself with a simple app.config setting to automatically utilize the default proxy settings on the box.  Neato burrito.

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