props.Node: add remove() method that removes the node it was calleed on

Browse source 
from its property tree. The node remains accessible as long as references
to it are kept. Example:

  var cow_chain = func {
      var cow = geo.put_model("Models/Fauna/cow.ac", geo.aircraft_position());
      settimer(func { cow.remove() }, 10);
      settimer(cow_chain, 2);
  }
  cow_chain();
