Added getTrapStatus() so that the Debugger can display trap information whenever a trap has just occurred, updated FileDump to store 'load' and 'exec' properties in MACRO-11 listing dumps (so that the individual machine files don't have to specify hard-coded 'load' and 'exec' values themselves), and added a new SerialPort parameter (upperCase) that can be used to force all received data to upper-case

Added support to FileDump for generating binary dumps from MACRO11 listing (.lst) files, since I wasn't having much success with dumpobj or obj2hex.pl; note that this assumes a listing file produced by the macro11 cross-assembler written by Richard Krehbiel in 2001, updated in 2009, and maintained here: https://github.com/shattered/macro11. There are other versions of macro11 floating around, like the one in the simtools project that accompanies simh, and the one built for the Windows-based PDP11GUI app.

Started centralizing the set of UNIBUS addresses, and adopted my first ES6 feature: octal constants (not the old-fashioned unofficial leading-zero kind, but the new "0o" kind); I will still use hex instead of octal whenever I can, but UNIBUS addresses are ALWAYS documented as octal, so I'm giving in....

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)
