Added support for paste to the VT100, but browser idiosyncrasies (eg, Chrome) are proving irksome; for now, you'll have more luck with Firefox, or sticking to machines that use a textarea for their I/O instead the VT100 if you need to do a lot of pasting

The VT100 is now smarter about detecting the host machine's physical CAPS LOCK state (and is also capable of displaying that state now)

Changed PC8080 auto-release timeout for key presses to use built-in setTimer() instead of the browser's setTimeout(), and reduced the timeout from 100ms to 50ms; let's see if the VT100 still experiences dropped keys when typing fast

Supoprt for tape images in the Absolute Loader format has been moved to the RAM component, so that those images can be preloaded into RAM in the same way that raw bootstrap images can; the RAM component now provides Absolute Loader image parsing as a service to other components that need it (specifically, the PC11 tape reader)

Updated PC8080 and PDPjs to support RAM images, eliminating the need for the old "writable ROM" kludge; RAM images can include their own load and exec addresses as part of the JSON file, but the RAM component can provide explicit overrides (if no load address is specified either way, the default load address is the starting RAM address)

Updated Closure Compiler to v20160911, so now we have a version that supports ECMAScript 6, but I'm not going to go bonkers on ES6 features just yet; the first feature I'm going to use is support for octal and binary constants (of the form 0onnnn and 0bnnnn)

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).
