- Changed the design for PersistentObject 1.5 for more clarity on the   ezcPersistentIdentityMap: - ezcPersistentIdentity map is now an interface to allow easier custom   implementations without inheriting the original code. - The add*()/replace*() methods are now consolidated to set*() methods to avoid   code duplication and user confusion. - The handling of named related sets is now extracted into own methods to   sharpen method signatures.
