ButtonDirective class

ButtonDirective adds all basic required a11y functional for any element, that are designed to work as a button (clickable icon, etc.)

This does NOT consume the triggering mouse event or keyboard event, so that if a transitive parent wants to listen to all events in it's scope (ex. click on anything to hide popup), it can do so.

Gives a common event trigger for keyboard, and click events.
