Solve dreaded "dictionary full" issue by segregating words into new
vocabularies delay-processing, password-processing, version-processing,
frame-drawing, menu-infrastructure, menu-namespace, menu-command-helpers,
and menusets-infrastructure. The net effect is to remove almost 200
definitions from the main forth vocabulary reducing the dictionary size
by over 50%. The chances of hitting "dictionary full" should be greatly
reduced by this patch.
