Recoded how 'handles' were implemented; these were extra wireframe edges

actually, adding vertices and edges to displist.

Now the subsurfer gives editvertices a pointer to the subsurfed vertex
location; allowing not only vertices in 'optimal' draw to show correct, but
also gives proper handling of borderselect and lasso for edges. :)
