Free42 state file switching, export, and import

[Thomas Okken]

I'm sure that a person who knows the HP-42S through and through could take a memory dump from that machine -- or an Emu42 state file, which I assume is basically the same thing -- and translate it to a Free42 state file. However, I am not that person. I only know the 42S from a user's point of view; I've never looked at the internals or ROM disassembly etc.
