Documented the MTPS (11/34A), MFPS (11/34A), and MFPT (11/44+) instructions, even though our basic model support (11/20, 11/40, 11/45, and 11/70) doesn't use them

Fixed a few (spurious?) WebStorm inspection warnings, and added some band-aid code to netlib.js so that PDP-11 machines running in the Node environment can fetch all their resources, whether local or remote

v1.31.0 marks our first transition to ES6 classes, but only for PDPjs initially (which is why there must be both /lib and /es6 files in the shared folder for now)

Eliminated the NO_FLAGS hack, which was doubly-annoying because its sole purpose was to prevent writes to ONE address -- the PSW -- from modifying any flags; the proper solution is to simply ensure that all flag updates occur before the destination is written

Fixed the evaluation of register operands for the XOR opcode (this slipped through the cracks, since it doesn't use readSrcWord())

Fixed RTI on older PDP-11s (ie, 11/20); the old RTI behaves like the new RTT, which did not exist on older machines

DEC's "TRAP TEST" finally passes (and I learned a lot about PDP-11 opcode idiosyncrasies in the process)

Cleaned up the PDP-11 updateDisplay(s) code, and removed the update hack inside the WAIT instruction; display updates now occur in sync with the machine's 60Hz clock

Refer to all 11/45+ instructions as 11/45, rather than 11/70, since the 11/70 doesn't appear to have added any instructions to the 11/45's set

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.

In the spirit of the PCx86 Debugger, the PDP11 Debugger can now distinguish between virtual and physical addresses; physical addresses are specified with a leading '%'; this necessitated special CPU memory interfaces that mirror the Bus memory interfaces, which perform mapVirtualToPhysical() as needed, with traps disabled.
