Manual/Auto slideshow

## Currently

`gnawrnip` is displaying the image in a slideshow of automatic.
But, I want to slide manually sometimes (many images. wait, wait ...)

## Want to achieve both

Use [jQuery.Cycle2](http://jquery.malsup.com/cycle2/)

## Forecast

require

```html
<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery.cycle2/20130801/jquery.cycle2.min.js"></script>
```

load

```js
$(".screenshot.animation").cycle();
```
