Title: Adding read-only Future, adding #once to EventTarget

Hi Yehuda,

I was working off of RSVP to split it into distinct Future and Promise concepts. This might not be very Promises/A+, but it seemed a little strange that a function could make a Promise and return it, allowing the caller to resolve or reject it. I don't imagine this is much of a problem in practice, but I thought it might be an improvement. I'm curious what you think.

I also added in EventTarget#once so that event handlers would clean up after they do their job.
