* Handling is now based on a list of RequestHandlers in VaadinService
* Request handling logic has been moved to VaadinService
* Users can customize the list by adding own (service level) request handlers
* For users specific request handlers you can still use the request handlers in VaadinSession
* Deprecated RequestType - all handlers are given the opportunity to handle a request until one of them chooses to handle it. RequestType makes no sense as it does not tell which handler will handle the request.
* Removed serveStaticResource which has never been used

Locking of a VaadinSession is now done in VaadinService using the underlying HTTP session. This enables locking of the VaadinSession even before it has been created.
