  * Each PropertyBag is aggregated with an EventSource, so that it is
  * possible to attach event listeners. The event name is composed
  * of "Bonobo/Property", the type of the event and finally the property
  * name - everything separated by colons. At the moment there is only one 
  * type defined - "change". So if a property with name "autosave" changes
  * its value, we emit an event with the name: 
  * "Bonobo/Property:change:autosave"
