Following commit 90d278, the object code generated by the python bindings of nanogui (github.com/wjakob/nanogui) went up by a whopping 12%. It turns out that that project has quite a few enums where we don't really care about arithmetic operators. This commit thus partially reverts the effects of #503 by introducing an additional attribute py::arithmetic() that must be specified if the arithmetic operators are desired.
