Adding the ability to have the pagination come before the slides.

Hi Nathan,

I have a case where the design I'm working on calls for the pagination dots to sit above the slides. That part is easy, all I need is a bit of relative positioning to pull them up top.

The problem I ran into was we have multiple slideshows on a page with varying height. So as you can imagine relative positioning doesn't work very well in that situation. I would have to class each slideshow and style them individually based on that particular slide height and that doesn't scale very well.

I need the pagination to come before the slides in the DOM. I changed the pagination option to accept 'append', 'prepend' and false.

Everything defaults to what you had set, 'append' and 'prepend' both pass as true in your checks.

I did think about using a more semantic approach:

```
pagination: {
  active:      true     // [Boolean] Auto generate the pagination.
  position:  "after"  // [String] Can be either "before" or "after".
}
```

But I wanted to keep my changes as minimal as possible until I got some feedback from you.

Thanks
