Sprites Modes

All sprites can now be displayed in either ECS Default mode, 140ns ( this is NOT ECS mode1 ), 70ns or 35ns on display resolutions eg. 35ns on a LoRes screen or 140ns on a Super HiRes screen.

Sprites are either 16, 32, or 64 bits wide. They can be attached in any mode ( formerly could not attach sprites in the ECS SHRES 35ns resolution mode ).

Can use any bank of 16 colours from the 256 colour palette for the sprite colours.
