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.

These functions appear correctly to model the NTSC and PAL palettes; the CRT's attempt to switch function doesn't work properly yet though.

Realised that phase time can fit inside a single byte, since it's always (well) within the first quarter of the line — and if it somehow weren't (?) then taking it modulo the frequency would do.
