* Move the BasicDOSProtector.cs to OpenSim.Framework (all useful classes belong there.....)

* Add an IsBlocked(string Key) method so it can be used more generically.   (think..   if we want to rate limit login failures, we could have a call in the Login Service to IsBlocked(uuid.ToString()) and ignore the connection if it returns true, if IsBlocked returns false, we could run the login information and if the login fails we could run the Process method to count the login failures.
