Virgil Dupras 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.

Virgil Dupras 41cd8086d4 forth: don't use "(entry)" in dummy.fs
Because icore.fs defines it in a "not-for-runtime" manner, dummy.fs
executing it had ill effects. We use a workaround instead.
