Working sender, listener, daemon

Listening and sending for full message.
Changed messaging to be able to handle sending on 2 separate ports.
Made a working daemon (without fully functional logging on Mac).
Deleted Message Spec

Unnecessary because any needed info is in Messaging/header/message.h
Re-added closing stderr

Closing stderr works on RPi (but not on Mac) so added it in.  Also
added \n to printing message.
Working forward from messengerd

messengerd will now forward messages to message.receiver_hostname
properly.
Also added comments to messaging.h for files
