Title: streaming view rendering

Allows for a view engine to return a stream upon being asked to render a
path. This allows for the engine to simply stream out data as it is
loaded from disk (or other IO location) without having to collect it all
first and then send it.

Fallback mode for all existing engines that call `fn` upon completion
takes over if no stream is returned. This works for both app.render and
res.render
