[PyCrust] Better ZODB/Zope support in PyCrust

[Patrick K. O'B. <po...@or...>]

I improved PyCrust support for ZODB/Zope by extending the namespace viewer
so that it now allows you to drilldown into all the items stored in ZODB
BTrees, which act much like Python dictionaries. This enhancement is
available in the CVS version.

This has been tested with Python 2.2 and the latest StandaloneZODB. As I
intend to support ZODB as much as possible, please let me know any problems
you run into, or features you would like to see.
