Python 3 compatibility for functor division
This follows up on !2214 (merged) which introduced the __truediv__
decoration
of functors but missed __rtruediv__
.
In addition, fix math (stdlib) import in LoKiCore.math (functors that call math.log
will fail)
Must be applied together with Moore!592 (merged) (math.log
-> log
).
