Added a (temporary) auto-XON hack to the VT100's SerialPort component to prevent ugly buffer overflows when a PC is shoveling the data in too fast (to be replaced later with real flow-control interfaces)

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).

Cross-machine serial port connections are only half-working (need to defer initConnection() until all machines on the page have initialized their bus)

Starting on v1.24.0; first change: support for encoding ESC characters in SerialPort test strings (support which perhaps should eventually be moved into getComponentParms() instead)

Dual (connected) terminal configs should be working better, now that both transmitted and received data is clocked according to their respective baud rates

Enabled smooth scrolling, connected SerialPort UART transmitter status to the ChipSet FLAGS buffer (matching how the Keyboard UART transmitter status is connected), enabled binding of terminal I/O to the Control Panel output window (if any), and added simulation of received data at the programmed baud rate (but a better solution has been noted and needs to be implemented)

Added TEST control to exercise the VT100's 8251A UART (um, excuse me, the PUSART -- an awful acronym)
