As positively recieved on the mailing list and irc (and blessed by

guitargeek), this commit enhances the support for temporary storage
for the structs EditVert, EditEdge, and EditFace. The field
"EditVert *vn" has been removed and replaced by a union called
"tmp" that can hold:

 v,  an EditVert pointer;
 e,  an EditEdge pointer;
 f,  an EditFace pointer;
 fp, a float pointer;
 p,  a void pointer;
 l,  a long;

Please see the mailing list post here for more information about
this:
