1. Linebreaks separating variable declaration blocks

Discussion: https://github.com/roundcube/roundcubemail/pull/109#discussion-diff-6064999

I think for this, we will end up reverting some of the changes that I made. But we still have to discuss the details - It's just mainly about the other devs telling me in what instances it would be permissible to separate blocks.

I agree with Thomas that maybe this should happen in two phases. A lot of the time those variable declaration blocks should maybe be done in a totally different way anyways so maybe we should worry about that when we get to that. Maybe when we get to use composer more and can actually re-use composer elements from other projects.

Example..

$headers        = rcube_utils::get_input_value('_header', rcube_utils::INPUT_POST);

To me this seems overly convoluted. Ive always wondered why there isnt an input class.

$header = Input::post('_header');
