bus/nubus: Implemented enough for interlaced modes not to hang. Implemented more CRTC registers, getting to the point where System 6.0.8 and System 7.0.1 will show video on NTSC and PAL displays with approximately correct interrupt timings. Also implemented 1:2:1 convolutions (this blurs the image vertically - in real life it reduces interlace flicker). Screen update in interlaced modes isn't right yet - it updates every line on every frame, and there's a vertical offset caused by the initial half-line.
