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

Any time I pick my nose I thought "hey huh do I have brain damage" because I wouldn't expect to just randomly be gross with no input of my own, and I remembered on other codebases picking your nose was often an indicator your brain is hurty.

Keep sneezing in though, stuff that anyone can reasonably do on random is very neat and I like the hostage situation example Wrench brought up.
