Copland build D11E3

Copland build D11E3 is an unleaked build of Copland. It is an earlier compile of build D11E4, which is mentioned in the latter build's release notes documentary.

D11E3: The implementation of the Notification Manager in D11E3 is a simple non-functional stub, to only ensure that the calls return and do not crash. We are investigating adding some implementation for DR1 which will support the notification call back procs if/as required to enable compatibility applications to run.
