Chat notification sound also plays when a message is sent

[gergles]

There's an iChat style sound played whenever you send a message... then maybe 50 ms later the notification sound set for the chat also plays.

Only the iChat-style sound should play (and we should be able to disable it.)

So you're hearing two notification sounds? Weird - maybe I left some code in on accident in the messages sending process. I've been trying to form an app "event bus" to handle all of these events, so in the future it'll get cleaner, I hope.

@gergles Fixed the first half of the issue; the next part is user selection of default sounds (and optionally, no sounds) for individual events.
