Scoped slot pagination addon

[rafalolszewski94]

My suggestion is to provide scoped slot for pagination addon so we can write our own components for pagination.

Couldn't find anything in docs related to this.

Currently there's few params to use and it's called Slots Attributes, but in Vue it's called Scoped slots.

There could be more to control pagination and navigation for example:

• goTo(n)
• goToFirst()
• goToLast()

These would give a lot more control, since we already have currentSlide and slidesCount
