Added "halt on invalid instructions" and "continue on invalid instructions" commands, which do what they say on the tin.

Added new commands:
...
"draw invisible vectors" - displays non-drawing beam motion in red.
"hide invisible vectors" - returns to normal rendring mode
"step display" - runs until the next display rendering command completes, refreshes the display to allow easier debugging of display programs.
Console input buffer is now cleared after a break operation.

Added DCAM disassembly. Fixed annoying space-eating behavior in the CLI's command completion.

Implemented most of the PDS-4 display hardware enhancements (including BLINK, which is very important.) Implemented SBL and SBR, multiple indirects, and fixed decdoding of ACT 2 instructions. Rewired interrupt status bits (arbitrarily rearranged on the PDS-4). SSV4 now mostly seems to work, keyboard still non-functional.

Implemented decoding of PDS-4 display instructions, updated LVM decoding and execution (completely different from PDS-1). Execution of new PDS-4 display instructions not yet implemented; awaiting the discovery of code that uses them.
...
Tweaked color of point-plotted and vectors that resolve to a single point, brighter and slightly different shade of green for effect.

Initial swipe at refactoring display processor to allow separate PDS-1 and PDS-4 variants.
