[Mono-list] TweetSharp Failing

Hello again.

This is looking like a Mono bug to me.  If I edit TweetSharp's source
code to manually set the network credentials like this (at Ln 146,

var creds = new NetworkCredential(_username, _password);
var credCache = new CredentialCache();
var host = request.RequestUri.Scheme + Uri.SchemeDelimiter +
credCache.Add(new Uri(host), "Basic", creds);
request.Credentials = credCache;

then it will work.

TweetSharp relies on HttpWebRequest.  I've had a look through Mono's
System.Net/HttpWebRequest.cs source and it appears to me that it drops
the "Authorization" header.  This header is what TweetSharp uses to
send along authorization to api.twitter.com and works with Microsoft

Please let me know if this is a bug and I'll file a report with a test
case using TweetSharp.
