How about adding a context.listenToOnce(...)

[weiribao]

So that we don't have to do view.listenToOnce(context.vent, ...).

I can send a pull request but it is probably better to hear your opinion about it first.

@weiribao : I think it's a great idea. A PR would be most welcome.

@weiribao : Just curious to know the use case for the listenToOnce() api. Do you have an example scenario?

[weiribao]

@niki4810 All major event libraries out there have it, so I guess we should have it too ;-)
