core: add a new Base_viewFieldLibrary/my_view_mode_id

for editable id fields

This field is required, because ID are really required in Zope so we have to make an exception to prevent a Site Error message and has an external validator checking that the document has no pending activities.

+"""Refuse changing the id of an object with pending activities.

+document = context.aq_parent.aq_parent.aq_parent
+
+if editor != document.getId():
+  return not document.hasActivity()
+
+return True
