Allow cancelling of all autocomplete events

I would like to be able to cancel the close event, for weird client-requirement reasons.

It seems reasonable to make all the events cancelable. In this case of close, the code change is simple:

From:

this._trigger( "close", event );

this.menu.element.remove();

this.menu = null;

To:

if ( false !== self._trigger( "close", event ) ) {

this.menu.element.remove();

this.menu = null;

}
