Previously the client would only learn the mime type of what was being dropped on it once the drop occurred. To enable more sophisticated filtering of drag & drop, we now pass along the list of mime types being dragged to the client with each MouseMove event. (Note that MouseMove is translated to the various Drag* events in LibGUI on the client side.)
