48078d9c9c forth: Replace "SKIP?" with "(?br)" 
There is an alternate git history where I continued the Forth-ification of
words, including "SKIP?", but that was a bad idea: because that word was
written by flow control immediates, I stepped into quicksands where stability
became necessary in z80c.fs and I couldn't gracefully get out of it.

I'm stepping back and take this opportunity to replace the shoddy SKIP? algo
with a more straightforward (?br) implementation.

(br) and (?br) will always stay in boot code where it's easier manage a stable
ABI.

Ain't that not self-bootstrapping enough to your taste? Whoa, I'm

6eaabb9bbe forth: make word name of variable length 
This allows us to save a whole 500 bytes on the final binary size!

This change comes after I took a look at the hex dump and saw that one letter
constants in z80a.fs took a lot of space.

The removal of the "divide" routine highlighted the fact that
nativeWord wasn't properly stabilized.

This requires us to significantly adjust our build process, which
now has 3 stages.
