A (PC8080) VT100 can now connect to a (PCx86) IBM PC AT; only problem seems to be flow control now.

Also, each PCjs debugger can now be independently accessed from an external debugger (eg, "pcx86('ver')" or "pc8080('ver')"); the global '$' symbol is no longer used for debugger access.
TODO: There are still many places where GLOBALVAR should be replaced with PCX86.GLOBALVAR or PC8080.GLOBALVAR as appropriate (which I've finally started doing in each debugger.js file).
