Words of Lugforth

The words of the Linux build (out/posix/lugforth) and of the web build (out/web/lugforth.js), as the interpreters themselves list them.

Generated by tools/words_reference.py, which asks the interpreters for their words, so nothing here can be missing (run it again after adding words: see docs/dev/PITFALLS.md). The descriptions come, in this order, from the reference pages attic/oldsite/*.html, from short notes in tools/words_notes.py, and from the stack comments and bindings in the Forth sources. A word of the ANS Forth standard that the project does not describe is marked ANS: it does what the standard says (see the links below).

The columns: Word, Stack effect, What it does, and where the word exists: P Linux (POSIX) build, W web build.

The `forth` vocabulary

511 words. 62 are described by the reference pages, 162 by the notes, 155 are standard words the project leaves to the standard, 132 have only a stack comment or binding, 0 have no description yet.
