Don't allow players to friend or foe themselves

[Askaholic]

It doesn't make sense to allow friend/foe relationships to ones self. Are we supposed to hide our own chat messages from ourselves if we are our own foe? Are we supposed to be disallowed from playing a game with ourselves?

I think the client already isn't supposed to allow you to do this, but I can see in the server logs that sometimes this is attempted. I would be curious to know the number of self referential rows there are on prod.

select count(*) from friends_and_foes where user_id=subject_id;
