Add flag to video capture handler to indicate frame did not change according to render/GFX functions. Add code to AVI writer to support writing NULL non-keyframe video chunks to the AVI instead of feeding unchanged frames to the ZMBV encoder. Add dosbox.conf option to enable this performance and bandwidth optimization with future reminder to enable by default if option does not cause issues
