Pull Request for Issue # .

Summary of Changes

Use a global object named bootstrap instead of the Joomla.Bootstrap

WHY?

This is my fault, let me explain: Joomla has 2 instances (tabs and modals) where it kinda uses it's own constructor (eg some specific tasks executed before initialising the interactive elements). When I was implementing this JS part of BS5 I thought a Joomla registry was a good idea. Never ever ship code that was a nice idea. The problem is that Bootstrap documentation in such case is referring to objects that don't actually exist in the document. I'm sorry, this was a terrible idea

Testing Instructions

Check the dropdowns in the dashdoard
Check the modals in the Article Edit
Check the Accordion in the Menu edit (select new component)
Check the tabs in the tinyMCE plugin (set0... )

Actual result BEFORE applying this Pull Request

Bootstrap docs don't actually reflect the methods of the interactive components

Expected result AFTER applying this Pull Request

Code is the same but the Bootstrap docs reflect exactly what exists in our codebase

Example of the code that reflects BS docs

Documentation Changes Required

The Bootstrap Docs is our documentation but we still need to document the Bootstrap.php methods

@wilsonge sorry mate for the mess, this needs to be merged ASAP
