Fixed CPU start/stop control; runCPU is now strictly a worker function, not a control interface (PDP-11 only; other CPUs still need to be updated to match)

Converted all "short" references to "word", since word meant 16-bit in the PDP-11 world, and no one said short back then

Updated the build process to formally declare that we're compiling from ES6 to ES5 (although for now, 99.99% of the code is already and will remain ES5.1-compatible)

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)
