Special Orange request; support for SoftBody Goal weights for Lattices.
Animating detailed clothes with softbody becomes messy, so now we'll
try it this way. :)

It simply uses the W (weight) value, as already available in each Lattice
Point. Only had to make it editable;

- NKey panel
- or press W in editmode

Further there's a minimalistic W button in the softbody Panel!
