* 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)
* added mutex to client proxy to protect stream
* added try/catch to ipc log outputter buffer thread
* protected ipc client proxy list with mutex (saw a weird stl error, might be caused by cross-thread weirdness)
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.
