Added separate components for different behaviours of Modal vs Non-Modal.

Improves a bit the documentation

Adds simple tests

Adds a nice CSS only close icon to the dismiss button. Adds tab management, so only a few specific HTML elements can be selected using the Tab key. Handles backdrop with a simple fade animation.

Added .editorconfig to force spaces on my editor, fixed spelling and added a Modal component that supports stacking. console.log are left intentionally for reviewer to look into thought process
