This allows you to set your "sticky" chat channel, so that you will always return to the channel you want when you hit enter & not the channel that WoW decides to put you into. So no more /saying something that you meant for /guild, etc.

Made it save per Character, for servers that need different channels (i.e. for ironman using a channel vs guild)
