Node editor: when adding a new node, automatic links are created:

- from all selected nodes
- only connections between highest order socket types; so if there's RGBA
  and Value sockets, only RGBA sockets are connected. This because in
  these cases the Value sockets usually are for user input.
  Example: Mix node.

Thanks Trip for the hint!
