Log Message:
Added 'config.MultiKey()' and 'config.UnionOf()' configuration key classes,
to generalize existing specialty keys such as 'ProviderOf' and
'FactoryFor'.  (The latter two are now defined in terms of the former
two.)  Also, made classes and types usable as configuration keys.  This
was needed for the above generalization, but also makes many other
class-lookup concepts possible.  (Note that there may be some slight
changes to the effective registration and lookup order of these and other
configuration keys as of this change, as there were some previous errors
and/or ambiguities to the lookup order that were not covered by the test
suite.)
