More efficient if logic in CheckTimlines(). Added a flag for a feature of full copy savestates. This is a VBA/SNES9x type feature where a savestates full movie content can be loaded in read+write. Those emulators perform this option with a bit of trickery by not truncating the movie data until the next frame. Instead we are going to give the user an option to use this mode through the user interface.
