Log Message:
More cleanup/refactoring of URL handling and traversables/contexts:

- Most 'ITraversalContext' services are now available as attributes,
  rather than methods.

- Solidified the concept of a resource to include a fixed
  'resourcePath', and the ability of an interaction to determine a
  resource's URL.  Removed the need for traversables in general to
  know their location; this is a resource-specific matter.  It's now
  a cinch to turn a traversal context into the most-useful possible
  URL for the traversed-to item.

- Created a separate class for the root of a traversal, which makes it
  easier to start a traversal and allowed some conditionals in the
  TraversalContext class to be removed.

What we probably need to do next, is spruce up NOT_FOUND/NOT_ALLOWED
handling (which is rather broken right now).  Adding some tests for
resource  retrieval and URL computation would be a good idea too.
