[docs] 'new' module has unhelpful deprecation warning

[Michael Dyck]

At
     http://docs.python.org/2/library/new.html
(8.16. new — Creation of runtime internal objects),
it says:
     Deprecated since version 2.6: The 'new' module has been removed
     in Python 3. Use the 'types' module’s classes instead.

But the 'types' module doesn't export any classes, and the page at
     http://docs.python.org/2/library/types.html
doesn't indicate how it could be used to replace the functionality
of the 'new' module.
