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.

examples directory to support it. This is installed only on i386 for
now. It will be enabled in a later commit.
