renaming binding names for pre/post increment/decrement operators for…

 Miscellaneous
 -------------
 
-1.   The pre/post increment operators both map to ``plus_plus``, with the pre-increment operator being invoked via ``a.plus_plus()`` and post-increment via ``.plus_plus(0)``; just as the operators are technically defined in C++. The same is true for the pre/post decrement operators, both called ``minus_minus``.

-2.   User defined literals ``operator"" _foo`` end up being named as ``operator_foo``.
