- added to the cicBrowser support for displaying recursive direct/inverse

- added to the cicBrowser support for displaying recursive direct/inverse
  dependencies of a given object. To integrate this with cicBrowser's history
  also added a new URI scheme: metadata:/deps/(forward|backward)/URI, where URI
  is the object URI without the trailing "cic:"
- removed automatic stripping of #xpointer(...) from URIs of inductive types
