wings_body and weld function ...

Somehow this feature is iterating over empty parts of a vertex array and getting an "undefined" element sent to e3d_vec:average

I think I have circumvented the problem by save and then reload which should PACK the WEDS object. I don't want to just add a renumber into the weld process willy nilly if the fix should really be done elsewhere.
