StreamNavigators should also return Bundle resources

[wmrutten]

The Xml/JsonStreamNavigator classes implement special behavior for Bundle resources; the navigators return the contained Bundle entries, but not the Bundle itself.

The DirectorySource class uses the NavigatorStream classes to harvest summary information from the content directory. As a result of the above limiation, you cannot access Bundle resources on disk using DirectorySource.

Request:

• Allow NavigatorStream to also return Bundle resources
• (?) implement configuration option to control behavior
• Update DirectorySource to enable the new behavior and expose Bundle resources
