debugging, while still keeping the possibility for a Manager to delete
buggy objects.

MultiHook made the bogus assumption that hooks defined in classed would
use the same signature as hook functions added to instances. Well, they
*would*, but only after being transformed into bound methods. This means
that the before-publishing-traversal hook will have call signature
(container, request) as a function, but (self, container, request) as a
method, with self==container.

        could fail due to a broken "echo" implementation causing the 
        creation of a borked version.txt file.

- show warning only if 'title' is removable
- use 'form-element' class for textarea

split into small chunks even when initialized from a string.

      - Added a ZConfig directive 'large-file-threshold' to control
        the request content-size threshold at which a temporary file
        gets created. Use the same value for deciding between reading
        the whole request in memory or just a chunk inside
        webdav.NullResource.PUT().

      - Stitch newly-created object into it's container *before*
        calling it's PUT() method. This fixes an issue with
        OFS.File/OFS.Image that would result into reading the whole
        file in memory and wrapping it into a *single* Pdata object.

      - Import ZServer.CONNECTION_LIMIT variable *inside* the method
        that uses it. Before this, the variable was imported at the
        module level, thus binding it too early which would cause the
        ZConfig handler to have no real effect.

      - Catch AttributeErrors and KeyErrors raised from
        __bobo_traverse__ and convert them to NotFound. In debug mode
        a more verbose error message is issued, the same way it's done
        on attribute/item traversal.

      - Don't escape properties stored as XML (ie: having a
        __xml_attrs__ metadata set by PROPPATCH) when building a
        PROPFIND response.

      - If a PROPPATCH element value contains only a CDATA section,
        store the CDATA contents only.

      - Always unescape element contents on webdav.xmltools

      - Use saxutils to escape/unescape values for/from
        PROPFIND/PROPPATCH.

      - Make OFS.PropertySheet use the escaping function from
        webdav.xmltools.

      - Escape/unescape " and '

      - Set a default value of '' for the new 'alt' property as not to
        break existing content.

      - Collector #1443: Applied patch by Simon Eisenmann that reimplements 
        the XML parser used in WebDAV fixing a memory leak.
