Improved Mute Options

#1
Firstly, thank you so much for adding /ignore to the player list of available commands. It's very useful.

My suggestion to is improve on that by making /ignore work across all channels (including /cc City Chat). I have ignored a few people in my city and I no longer see their public chat posts, but I still see everything they post in the /cc.

It would also be nice to have a way to /mutecc or /disablecc for when you just want some peace and quiet. Yesterday I logged in to a bunch of gay bashing in /cc and today I logged in to see a lot of inappropriate racial and sexual commentary. The obvious solution is to leave the city, but there are people I like in the city and it would be unfortunate if I had to leave because of a few people who have no chat borders.
