Unified implementation of filters for CloneSources

Browse Source 
All filters now derive from FrameBufferFilter, which is always used in a CloneSource. Default FrameBufferFilter is Passthrough filter. Others are Delay and Image filters. Implemented UI selection of filter type, XML session save and load. Linked ImageFilter to Code editor.
