Remove random emotes or at least have a way to disable them

[Wrench-1]

Never really given too much thought to this personally, but I'd be down for this change for at least some emotes, but not all. Burping and Nose Picking should be removed from the random pool because they're pretty damn gross and most times it just makes rather serious moments a tad awkward. A few should stay, however. I believe sneezing is part of the random emote pool, and I'd like to keep it for stupid reasons that I personally find funny, such as having five people say, "bless you" during a hostage situation.
