Hook Modifier: add falloff & radius options

- Add falloff types & curves (matching warp-modifier)
- Add uniform scale option,
  important when adding hooks to non-uniform scaled objects,
  especially for use with lattice objects which can't avoid uneven scaling.

  This uses relative transformation set when the hook is assigned,
  when measuring the distances.
