Attempted to generalise on pixel counter storage, at least. Further adjusted background timing but I'm still not sure.

Added something of the ball counter, but without yet a working HMOVE it's prone to error.

Generalised slightly, to allow events to be queued up to eight cycles in advance; most importantly each event gets to pick its own delay.

Introduced a four-cycle delay between playfield fetch and display, curing Yar's Revenge. Also disabled barrel roll scanling colouring again. I really need to make my mind up on that.
