implement "quit", the top level word

this is a real milestone, wow.

this required changing a few things in "interpret".

first and simplest, it wasn't properly dropping the word string when processing a number in compile mode.

second, "word" wasn't properly skipping whitespace - it was still becoming part of the word, which resulted in lookup failures.

third and most interesting, "interpret" no longer loops, it relies on "quit" to do that. that means that instead of cold_start handing off to "interpret" as it previously did, cold_start now hands off to a trampoline it creates that calls "interpret" just enough times to create and invoke "quit".

Force-Push: yes
