Implement multiple inheritance in Help, allowing variables, fields and related

Browse source 
topics to be inherited from multiple entries.  Operation/Help now also gives
the help hash a default ISA array, to make downstream processing by tests and
documentation compilers easier.
Convert existing Help entries that already used ISA to have an array ref
instead of a singular hash ref.  Also update the Help skeleton to show
the new syntax.
