Children should be a ReactRender instance

[natefaubion]

Likewise, getChildren should just yield Children.

Maybe this is related:

purescript-react/src/React.purs

Lines 415 to 417 in 14b4c22

	createClassStateless' :: forall props render.
	ReactRender render =>
	(props -> Array ReactElement -> render) -> ReactClass props

Children here is Array ReactElement but maybe it should be another ReactRender instance?
