vector3d scalar operator/ and operator/= no longer multiply by the inverse but use the expected division.

Browse Source 
That was a bad case of premature optimization.
Multiplication is indeed faster, but when working with floats this can introduce some rather unexpected inaccuracies.
Like x/x suddenly no longer being 1.0 (something guaranteed by division). 
If someone really needs this back, then please add some new function which makes it clear we don't just have a typical division here.
