Started working on save/restore support for the PDP-11; still a lot of state left to capture, but the basics seem to be working

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)

Numerous changes to make paper tape configurations more consistent with disk configurations. This allows all devices to share the machine-wide "autoMount" configuration object, now that the PC11 has a proper device name ("PTR"), making its properties distinguishable from those for RK11 and RL11 drives (eg, "RK0", "RL0", etc). And all the tape/disk components now use "Load" functions to connect a tape or disk to a device ("Attach" is deprecated). And finally, all tape/disk components now support operations to deposit their media directly into memory -- although in this case, the names of the operations are necessarily different: "Read" for tape images, "Boot" for disk images. The difference is partly historical convention but also reflects the fact that a "Boot" operation is more limited: paper tapes were designed to be completely loaded into memory, whereas bootable disks are designed for only the first sector to be loaded and executed. Also, paper tape images are now flagged as non-auto-starting, because they often require some user action (eg, loading another tape, setting some switches, etc), whereas disk boot sectors are flagged as auto-starting (see the fStart parameter of the loadImage() interface in the RAM component).

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
