wrapper for nodes

[plandolt]

I was in need to have a wrapper div on the node level containing all content elements within the node. This way I am able to define id/class to the node for styling. Then I can include this node anywhere and have it styled without any further configuration (like doing the wrapper when including the node). I hope you get the idea behind :)

Thanks for contributing! Haven't we introduced wrappers already in https://github.com/terminal42/contao-node/issues/13? What's different here? :)

The implementation in #13 does the same but you need to do that everywhere you include nodes. This is not practicable when including a node on several pages where you need to have a wrapper with a consistent class. This PR implements a wrapper configuration on the node level to encapsulate the content elements within the node definition.

I see. Implementation-wise I would also like to have that template based, so that's one thing to adjust for sure. But conceptual-wise this sounds okay to me. Wdyt @qzminski?

[plandolt]

I see your point. But I might need a little kickstart info to how I should implement a template based info.

I would also like to see an extra field in the wrapper subpalette where you can select a partial frontend template (e.g. node_default.html5) used to render that wrapper. So if wrapper is enabled, the $buffer in generateBuffer() method should become:

if ($nodeModel->wrapper) {
    $template = new FrontendTemplate($nodeModel->template);
    $template->setData($nodeModel->row());
    $template->buffer = $buffer;

    $buffer = $template->parse(); // to be returned
}

voilà 😀

Look pretty okay to me, @Toflar ?
