PDP11 and All VAXen: Support dynamic fetching of ROM or other boot code

Browse Source 
Simulators built with DONT_USE_INTERNAL_ROM defined will not have hte
binary of the needed ROM or boot components build into the simulator
binaries.  However, they will automatically and transparently fetch the
neeeded ROM or boot code from the web when these binary files aren't
available locally.
