Consistency of encoding / associatedMedia

Use the same definition for encoding and associatedMedia,
as they are synonyms for one another. Also make the definition
agree grammatically with singular vs plural.

Also refer to "CreativeWork" in the description rather than
"creative work", as the former seems to be the predominant form used
for properties on CreativeWork.

Add breadcrumbs back for Enumerated values

As enumerated values are not declared as subclasses of any
given type, our logic was skipping the creation of the
breadcrumb type hierarchy. Fall back to checking for typeOf
and creating a hierarchy that way.

Fixes #10
