classes: Add a check that arguments to classoids are themselves classoids.
...
Introduce a new word-prop that makes tuple-class words classoids at parse-time so that
self-referential tuple definitions with maybe{} work, e.g. TUPLE: node { next maybe{ node } } ;
Add unit test.
Fixes #766 .

Refactor the lexer/parser to expose friendlier words for scanning tokens. The preferred top-level words now throw an exception on EOF.
...
CREATE -> scan-new
CREATE-CLASS -> scan-new-class
CREATE-WORD -> scan-new-word
CREATE-GENERIC -> scan-new-generic
scan -> (scan-token)
scan-token now throws on eof
(scan-word) returns word/number/f
scan-word now throws on eof
scan-word-name expects a non-number
Fixes #183 .
