removeSpring event is not fired

[RichardGale]

from World.js

/**

• Add a spring to the simulation
• @method addSpring
• @param {Spring} spring
  */
  World.prototype.addSpring = function(spring){
  this.springs.push(spring);
  var evt = this.addSpringEvent;
  evt.spring = spring;
  this.emit(evt);
  evt.spring = null;
  };

/**

• Remove a spring
• @method removeSpring
• @param {Spring} spring
  */
  World.prototype.removeSpring = function(spring){
  var idx = this.springs.indexOf(spring);
  if(idx !== -1){
  Utils.splice(this.springs,idx,1);
  }
  };

Noticed while playing with the p2.renderer as that depend on the addSpring and removeSpring events. Removing springs does not remove them from the renderer.
