Jeremy Benoist 1565a6819a Add .gitattributes to slim down composer packages
When composer is used as a dependency manager for large web apps, transferring lots of extra files (such as tests and documentation) can be very time and bandwidth consuming. By using .gitattributes we can tell composer what files to ignore when distributing through composer.

Also, adding some extra space.

## Requirements
By default, this lib will use the [Tidy extension](https://github.com/htacg/tidy-html5) if it's available. Tidy is only used to cleanup the given HTML and avoid problems with bad HTML structure, etc ..
Since Composer doesn't support suggestion on PHP extension, I write this suggestion here.

<h1>3D Touch &#8212; будущее мобильных игр</h1>
<div class="postdate">Автор: <strong>Сергей Пак</strong> | Просмотров: 1363 | Опубликовано: 14 сентября 2015 </div>
<div class="entry">
<p>Компания Apple представила новую технологию 3D Touch, которая является прямым потомком более ранней версии Force Touch &#8212; последняя, напомним, используется сейчас в трекпадах Macbook Pro и Macbook 2015. Теперь управлять устройством стало в разы проще, и Force Touch открывает перед пользователями новые возможности, но при этом 3D Touch &#8212; это про другое. Дело в том, что теперь и на мобильных устройствах интерфейс будет постепенно меняться, кардинальные перемены ждут мобильный гейминг, потому что здесь разработчики действительно могут разгуляться.<span id="more-22030"></span></p>

<p>Итак, просто представьте себе, что iPhone 6S &#8212; это, по большому счету, отличная игровая приставка, которую вы носите с собой, а еще она может выдавать невероятной красоты картинку. Но проблема заключается, пожалуй, в том, что управлять персонажем в играх довольно трудно &#8212; он неповоротлив, обладает заторможенной реакцией, а игровой клиент зачастую требует перегруза интерфейса для того, чтобы обеспечить максимально большое количество возможностей. Благодаря трехуровневому нажатию можно избавиться от лишних кнопок и обеспечить более качественный обзор местности, и при этом пользователь будет закрывать пальцами минимальное пространство.</p>
