apply() operator

See original GitHub issue

To make it easier to use the reducer pattern in Cycle.js apps, we could implement a .apply() operator, that takes a stream of functions and an initial value and does stream.fold((value, function) => function(value), initialVal). You could define this very trivially on your own, but I feel that it would do better in the core.

Thoughts?

(P.S this is the 100th issue 🎉 )

delay(period) is stream.map(v => xs.periodic(period).take(1).mapTo(v)).compose(flattenConcurrently()) debounce(period) is stream.map(v => xs.periodic(period).take(1).mapTo(v)).flatten() concat(stream1, stream2) is xs.merge(stream1, stream1.last().mapTo(stream2).flatten())

@Hypnosphi Interesting. Those are pretty complex to write and understand though, so maybe @staltz has a point there. Because this is so simple to define on your own, maybe it’s not worth putting it in core.
