Patching Dexterity Container to use AddPortalContent for manage_pasteObjects

monkey.py

from plone.dexterity.content import Container
# Change permission for manage_pasteObjects to "Add portal content"
# See https://dev.plone.org/ticket/9177

# XXX Find a way to do this without patching __ac_permissions__ directly

            modified_mapping = (perm, modified_attrs)
