[2.0][suggestion] pass v-on event handlers on functional component

[kazupon]

Sometimes, there are times when we pass v-on event handlers to render function arguments on functional component.

The below URL is implemented example with v-bind on functional component.

In example, we need to define handler in props.
I think that come in useful by v-on event handers passing through.

var on = { valid: props.onValid, invalid: props.onInvalid }
 var vnode = h('validate-input-control', { props: props, on: on })

why gather the properties from props since there is props passed already? Seems duplicated.

In virtual-dom system of vue 2.0, when we are necessary in order to communicate the parent-child components, need to use the on.

I think it's more straightforward to have only props as the second argument. We can pass the raw data as the 4th argument, since it's going to be rarely used, only for advanced users.

That's sounds good.
I'll try to fix now.
