[Basics::] Basics.

Some fundamental definitions, mostly declaring object types to the Foundation
module.

@ Every program using //foundation// must define this:

@d PROGRAM_NAME "inweb"

@ We need to itemise the structures we'll want to allocate. For explanations,
see //foundation: A Brief Guide to Foundation//.
