Log Message:
* Added 'binding.Constant(key, value)', which allows you to specify
  a constant value to be used as a property or utility in that
  component subtree.

* Added storage.get/begin/commit/abortTransaction() APIs for ease
  of use in short scripts.  Defined a default provider for
  ITransactionService in peak.ini that provides each component root
  with its own TransactionService instance.  It's easily replaceable
  with other allocation strategies, if it should be needed.  I may
  change this later to a per-root strategy, since the current strategy
  requires creating localConfigs for each component root.  We'll see
  what actual use has to say about the best way of doing it.

* Fixed a problem with local/global config object startup that could
  cause "phantom" configuration objects to appear via recursion of
  getLocal() or getGlobal().

* Got rid of binding.meta.assertInterfaces, which is no longer needed
  because the Interface package now correctly handles metaclass
  instances.

* Got rid of Singleton, since it's not used for anything and I could
  neither think of any use cases nor remember why I added it in the
  first place!

* Made it possible for CachingProviders to cache per-localConfig as well
  as per-object.  This is handy for implementing per-hierarchy services,
  like the TransactionService provider mentioned above.

* Misc. TODO updates.
