when trying to get attributes during acquisition.  For example, it was
common for acquisition to mask errors occuring when trying to load
object state from the database, since this is typically triggered by a
getattr call.  I wanted to do something like:

  try: foo.bar
  except AttributeError, v:
    if v != 'bar': raise # Bogus attribute error
    # keep looking up the acquisition tree

Unfortunately, this fails because v is (sometimes) an
instance, not a string.

For now, we'll check for attribute errors, but ingore the values.

Brought ZDOM more in line with DOM spec by changing Root class to be an Element sub-class. Now the top-level Zope object is a normal Element, not an Element/Document/DOMInterface hybrid. Also added Document and DOMImplementation classes.

Added permissions to ZDOM classes.

Hide the delete button if the user doesn't have 'Delete objects' permission. Hide the export button if the user doesn't have the 'Import/Export objects' permission.

Added a 'getobject' method to ZCatalog. This makes it easy to retrieve a cataloged object from the searchResults list.

Fixed a problem in setting user permissions.
