Render to Writer instead of string (#39) The Render function has been changed to take a `Writer` instead of returning a string. This makes it possible to generate documents without having the whole content in memory. This also removes the `gomponents.Write` function, which is now redundant. Furthermore, the `el.Document` function has been changed to only take one child, as multiple children never make sense for it. (It's not even a child, more a sibling.)
