Remove CFWL_Note.

This CL removes the CFWL_Note class. The two subclasses, CFWL_Event and
CFWL_Message are distinct types and should not be related by the subclass. The
code has been updated to pass the correct types as needed.

The various FWL_EVTHASH and FWL_MSGHASH defines have all been removed and turned
into an FWL_EventType and FWL_MessageType enum classes.
