Virgil Dupras 6368cc3bac Remove (sysv) 
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.

Virgil Dupras d0c5d3a741 Forth self-bootstraps!!! 
This commit cuts Forth's dependency on zasm. It now self-assembles
its own boot-binary! Things are a bit messy now, I'll clean up
later.

Virgil Dupras 80985460d4 forth: remove JTBL 
We refer to stable offset as direct numbers instead of offset to JTBL.
Simpler that way.

Virgil Dupras 67c55b0b2f forth: Forth-ify ROT, a native word! 
This requires us to significantly adjust our build process, which

Virgil Dupras ca7c21d49f forth: make "(entry)" call WORD itself 
Otherwise, when a defining word would be called outside a definition
itself, it would get the name of the last parsed word, that is,
itself!

For example, dummy.fs, instead of creating a "_______" entry, created
a "(entry)" entry...
