 After this patch, IntegerModRing's inherit properly from categories:
 {{{
     sage: Z3 = IntegerModRing(3)
     sage: Z3.category()
     Category of fields
     sage: TestSuite(Z3).run(verbose = True)
     running ._test_additive_associativity() . . . pass
     running ._test_an_element() . . . pass
     running ._test_associativity() . . . pass
     running ._test_category() . . . pass
     running ._test_elements() . . .
       Running the test suite of self.an_element()
       running ._test_category() . . . pass
       running ._test_not_implemented_methods() . . . pass
       running ._test_pickling() . . . pass
       pass
     running ._test_not_implemented_methods() . . . pass
     running ._test_one() . . . pass
     running ._test_pickling() . . . pass
     running ._test_prod() . . . pass
     running ._test_some_elements() . . . pass
     running ._test_zero() . . . pass
 }}}

 This is required to use the cool features from #7555.
