HTTP listener in TrackerSample doesn't work / Can't use 0.0.0.0 to listen for HTTP requests

[ManlyMarco]

In latest master branch, System.Net.HttpListenerException: 'The request is not supported.' is thrown when trying to start the HTTP listener.

Cause: prometheus-net/prometheus-net#62

Changing this line https://github.com/alanmcgovern/monotorrent/blob/master/src/Samples/TrackerApp/Main.cs#L97 to TrackerListenerFactory.CreateHttp ("http://*:10000/announce/"), removing httpEndpoint above, and running the app as administrator finally makes it work.
