add send helper

This allows you to call actions on the reference from the template. emit is a jQuery term I believe, we could name it something like invoke or something else, doesn't matter.

Thanks @kellyselden, this looks great.

What do you think of naming it send instead of emit?

{{name-form actionReceiver=nameForm}}

<button {{action (send nameForm "reset")}}>Reset</button>

I like that name. Updated.
