Carousel - Pagination parameter is obsolete

[tauchter]

Even the pagination parameter is defaulted to false the pagination gets rendered anyways. The probable cause its that on the plugin initialisation the following assertion is not done:

this._options.pagination !== false

Same thing its happening on the _updatePages function

[atma]

Instead of adding an additional checks where the exact value is not important better to use truthy/falsy values. In this case should be if (this._options.pagination) { this._addPagination(); }.

I am on it, the PR is on the way.
