- Workaround for Collector #1081: The 'title' property for objects
       derived from OFS.Folder or PropertyManager can now be
       removed and replaced with a ustring property. This allows the usage
       of non-ISO-8859-1 or ASCII charsets

and replaced with a ustring property

Two new methods have been added to WebDAV resources, "manage_DAVget"
and "listDAVObjects". These are now used by WebDAV instead of the
earlier "manage_FTPget" and "objectValues". This separates the
permissions, and allows WebDAV specific overriding of these methods.

Make 'publisher-profile-file' configuration file setting work.  Note that the environment variable "PROFILE_PUBLISHER" has been banished with this change.  We also change the core of Publish.py to not conditionally define functions in order to have a bit more control over the process.

- rearranged order

     - Collector #951: DateTime(None) is now equal to DateTime()

     - Collector #951: DateTime(None) now raises a proper SyntaxError

       in the Zope Book.

flattenInterfaces now walks recursivly into tuples. Tuples are used if the __implements__ declaration is like (IFoo.__implements__, IBar)

some Zope products.

- Fixed BaseRequest's traversal loop. (Collector #1079)

Fix after namespace issue fix.  Because 'action' always exists in a manage_options entry for an item, its existence in the entry is not a reliable indicator that the entry is not the "View" tab.  Since it was tested for by "has_key", the View tab always pointed back to the current page (manage_workspace).  We fix it here by using "get" instead of "has_key".

Revert feature of never updaing metadata if index is specified in catalog_object.  This broke several applications.  Instead, we provide the catalog_object method (and the Catalog.py's catalogObject method) with an update_metadata keyword argument.  If the update_metadata keyword argument is set false (the default is true), metadata is not updated.

Merge 'dont-update-metadata' fix from 2.6 branch.  When the caller specifies that only a particular set of indexes should be updated, don't update the object metadata unconditionally.

This unifies the convention in templates, scripts, and Zope 3.

'default' are still fully escaped.
