Added 'all packages - definition.py - illustrate' (di*) command.

Use (g di*) to illustrate all segments.

Candidacy protocol means that segments without changes will leave the
filesystem as-is.

NOTE: This means that you can run (di*) regularly as a type of scorewide test
while working.

Also good for ongoing scorewide tests are ...

    (s dt*)
    (s pt*)
    (g dc*)
    (g di*)

... and probably a few related commands.

These are all designed to allow for frequent runs as proof that nothing has
changed.
