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...

The goal being to add a new native code dict staging phase.

This should help with upcoming challenges in bootstrapping z80 code
compiled through Forth.

The commit ended up being much bigger than anticipated. This was a long thread
of underlying complexities. This lead to the creation of interesting concepts
such as (sysv).

You'll soon see where I'm going with this...

Modest first step

It's not really an App.

Also, un-IMMEDIATE "LITN" it didn't make any sense.

It turns out we have to...

Forth-ification of Collapse OS goes forward. What will happen is that assembly
code in apps/ will become Forth code. The concept of an assembler code library
will become obsolete.

However, Forth's core use some of that code. To facilitate the transition, I'm
inlining that code directly in Forth's code.
