make it suck back generated primary keys. Restructured ListEntry so that most most gets are via Session.get() rather than by query. Added new methods to AttributeService to handle ListAttribute specific operations. Added a little more testing for AttributeService. I'm praying that the build will be repaired, since my efforts having been doing so much lately. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@5553 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
