Removing jQuery from Carousel

[Johann-S]

Rewrite our Carousel plugin without jQuery

• Improve off method of our EventHandler to remove listeners in an entire namespace

Work in progress...

Why not use Object.assign?
I thing another issue is that this implementation is deepCopy but $.extend by default is not recursive.

[wojtask9]

If Object.assign cannot be used I would use arguments (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/arguments) and then you can change Util.extend(Utils.extend... to Util.extend(obj1, obj2, obj3, ...)

I didn't had time to think more of this implementation of extend but it did the job 😄
I'll take a look thanks @wojtask9 👍
If you want you can submit a PR which target this branch (v4-carousel-without-jquery) with a better implementation

last issue here, when I call dispose the first time all the event listeners were removed, but if click on the next arrow (a new carousel is created) and if I call dispose again the listeners are alive 😢

[Johann-S]

I should improve my off method to allow to remove all the event but not only for namespaced events for example :

EventHandler.off(element, 'click')

// Currently
EventHandler.off(element, 'bs.carousel')
EventHandler.off(element, 'click', myHandler)

All test passed except one from our Button plugin but it's a known issue
