"Local Mute" for Orange Chat

[Krex]

Title says it all, I guess.
The option is there and works for the normal chat, but since people only use the orange chat to send messages to all players, it's kind of useless as of now.
You could argue that you could miss people calling for a tome or something, but to be honest, most players now when to take what action and if someone managed to annoy you so much that you had to mute him, they're probably not going to send anything productive anyways.
