Fix class member division operator.

Browse source 
Define the nb_divide/nb_inplace_divide slots in the interface and use it them as nb_divide/nb_inplace_divide for Python 2.x and as nb_true_divide/nb_inplace_trus_divide for Python 3.x.

The Python 3.x nb_floor_divide/nb_inplace_floor_divide slots (operator // in Python) are not populated by the interface.
