The transforms classes into ERP5Type were moved to PortalTransforms product.

 To keep the backward compatibility with the persistent objects which were not updated yet (ie.: Inside old business templates), it was added the some imports from PortalTransforms.

 Without this patch the persistent objects becomes broken and not accessible or updatable by Subversion and cause problems to update erp5_core.


 XXX Please remove this path once portal_transforms is not used or once all objects are already moved to latest versions of ERP5 (after transforms be moved at least).
