Add store.one() method to store.on.js about store HOT 2 CLOSED

Store is extensible; if you do it like this, you make it available for all namespaces and storage areas:

store._.fn('one', function(key, fn) {
    if (!fn) { fn = key; key = ''; }// no key === all keys
    var s = this, _fn;
    return s.on(key, _fn = function(e) {
        s.off(key, _fn);
        return fn.apply(this, arguments);
    };
}

As for adding it to store.on, i'm not digging the store.one() naming. If you aren't friendly with jQuery.one, then it doesn't look like an event method. store.onOne is clearer, but admittedly less graceful. Maybe store.once? Argh. I'd like to believe there's always a perfect name, but alas... Failing that, what do you prefer?

I like store.one(). I know not everyone uses jQuery, but it is pretty ubiquitous.

I also like store.once(). I think that's a good compromise, and it clearly indicates what it does. I'm not sure why jQuery didn't go that route. It's much clearer.
