* A few more fixes to HttpServer.

* http://www.codeplex.com/webserver/WorkItem/View.aspx?WorkItemId=3110 fix erronious call to beginread that caused an exception which was caught and ignored (increase performance)
* Pass socket into httpclientcontectImp and call the disconnect + reuse method so the socket can be reused quicker (increase performance)
* Ensured that in every error scenario beginAccept is called (stability)
* Fixed header casing (standards compliance)
* Fixed Connection: close handling (standards compliance)
