	Add abstract methods to the ChangeEvent hierarchy
		
			
			There is some common information in the ChangeEvent hierarchy, such as the type string, the change, and the project, that is not expressed in the old POJO hierarchy. Add a few convenience methods that can be used if the user has just a ChangeEvent, but which do not affect the JSON serialization. Change-Id: I22aadf76835528a63743bd758b5d6868dad212ed
