* added non-pod data support to events (event delete can now call dtors)
* improved cleanup of ipc message objects (because of non-pod event data support)
* moved the "message received" event up to ipc server and client (passed on from proxies)
implemented ipc "hello" message (to identify client type)
integ tests working for hello message, but use of ipc in main program has problem with events.
