Undo: implement undo of depth and duration editing

This was a bit different from the other editing commands:
1) Only the current dive is edited not all selected dives.
   Therefore, create a function that turns the current dive
   into a one-element list.
2) The profile has to be replot. Here, likewise, create a
   function to do that.
