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.

Tweaks for interrupt handling; added one instruction delay after ION before enabling interrupts, interrupts are now clocked on the leading edge of the processor Fetch cycle rather than on every clock cycle.

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

More PDS-4 work; most of the PDS-4 main processor instructions are implemented though not thoroughly tested (no software that has been unearthed of uses most of them). The byte-wise instructions have not been tackled yet.
...
MIT DADR behavior is corrected, now acts as a toggle. Single point plotting is now brighter than vector drawing for emphasis. Minor correction to disassembly of HLT instructions. Move config options to a new Configuration class, will someday be more sophisticated.
