This commit changes all the [Object]Allocators from the Client into a PerType<ObjectStore> member that contains a bunch of ObjectStore acting on ObjectBase. Adds a new (template) member functions to the client, Make/Get/Free that act on any object type, and update all the uses of previous [Object]Allocator to use these new methods. Also removes generated code that was generated per object type in favor of using the type-generic ObjectAllocator.
