"Buddy" system

[madmaxoft]

Let players decide they are buddies, so they automatically share all their areas, can build on one another's areas, allow or deny friends etc.

Q.: Do we make the buddy relation symmetrical, or not?
Symmetrical is more "brotherly", but requires acceptance from the other player (otherwise anyone could buddy an admin). Single-direction ("I trust him, so I give him my areas") would be easier to implement.
