Cleaned up dnd code

* added a destroy method to TerminatorTerm so
    a term can be destroyed with its corresponding vte and hbox
  * splitaxis now creates a term and add it to the receiving term
  * closeterm now remove the term and destroy it
  * added Terminator.add(widget, term, pos) add a term to widget a pos
  * added Terminator.remove(widget) removes a widget from the Terminator view
