Prevent Sleepers from getting monument ownership

Hey jtedal!

Monument Owner has a tendency to assign monument ownership to offline/sleeping players. Players repeatedly complained about Harbor monument being assigned ownership to a player over and over again, which frankly is quite annoying and defeats the purpose of Monument Owner. It turned out sometimes players log out on their tugboat while being inside Harbor's boundaries, prompting Monument Owner to this behavior.

In one case I teleported the sleeper into their base to make it stop, in another case I used killplayer to break the loop.

Please check the code and add checks so that sleeping players can't become Monument Owner.

Thank you for your great work!
