Vector.scale

[cline]

It would be nice to have an isotropic scaling method in Vector, analogous to Vector.scale but taking a single parameter instead of three. I implemented such a function in a script I'm working on and I noticed that fcvec.py (used by the Draft modules) does the same. Surely, others will use the method once available.

Can I request ths method, maybe called scale1, be added?

I have added the new method "multiply" which accepts a single float for the scaling.
