Rework of Layered path resolutions that make snapshots of stores containing layers

Browse Source 
actually capture the repository context at snapshot creation time. 
Gave ListEntry and MapEntry proper equals() and hashCode methods and backed out 
hibernate-cfg.properties changes.  Doh!  
Added cache configuration for AttributeService entities.
Did some warning removal in a few places.
