Switches to latching video interrupts until acknowledged.

Seems to fix Cisco Heat, at least. I have no idea whether I'm latching the correct thing, whether IACK should clear both or only one, etc.

Rejigs the video stream to ensure shifter really is continuous.

... and definitively to avoid potential buffer overruns. Or, at least, to have a mechanism in place definitively to avoid them. Which will be tested and debugged as necessary.
Also simplifies the colour burst and border/pixels selection logic.

Fixes RTR: the whole top half of the SR should be preserved.

Specifically, the 68000 Reference Manual says: "The supervisor portion of the status register is unaffected." Clearly when I first read that I misread it as the supervisor _flag_ (rather than _portion_) should be preserved.
