Closed issues #5 and #6

Updated dependencies and fixed resulting regression breakages resulting.  Please be sure to  change the dependencies in your nuspec if they aren't handled automatically.  I updated all of the signalR references to point to the Microsoft.AspNet libraries, which appear to be the new trunk for SignalR.  I also brought the MVC example back inline with dependencies.  Also coded the ability to have the appender communicate with a remote hub (my real motivation for touching the code).
