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.

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.
