Merge pull request #2567 from saschagehlich/bugfix/scroll-to-center-deprecation

Make sure SelectBox does not use the old scrollToCenter API
Improved limit()/clamp() behaviour - now it doesn't call nor(), reusing the
(needed anyway) len var, resulting in *one* scl() call instead of *two*.
Also, we use cached len, so that we don't have to calculate it twice.
Mostly beneficial for Vector3 class.
Provides a) optimized limit()/clamp(), b) new limit2(), setLength() and setLength2() methods to all Vector classes (Vector interf., Vector2, Vector3). Also removes the docs that should are inherited from Vector interface in Vector2/3.
