Changes to properly daemonize the server

[subtle-supernova]

It's currently not possible to make the server a daemon using tools like sysvinit or the newer systemd. Initial experiments to force the current codebase to do so resulted in failure due to the system's reliance on input from stdin to do things like proper shutdown.

I think the proper solution to this is to change https://github.com/subtle-supernova/Core3/blob/unstable/MMOCoreORB/src/server/ServerCore.cpp from a loop that listens to stdin to a loop that listens on a socket. This not only allows us to use a proper init script but will allow us to create more diversified tools for communicating with the server.
