Return to term list after multiple add, not vocab list

I often need to do several "add multiple term" steps, so I would prefer to see the function return to the term list, rather than the vocabulary list. Its also nice to see that the terms have been added and that they are correct (they always are, but its still nice to see). I have created a patch for this - its super simple too.

The multiple add feature alone makes this a great module. Thanks for saving me hours of copying and pasting terms one at a time.
