menu item without text becomes a divider

I would like to be able to have a menu consisting of only icons or images.

Currently that's not possible, and an item without text becomes a divider, and will behave oddly.

I ran a full grunt on this.

-

ui/widgets/menu.js:515

	_isDivider: function( item ) {
		// Match hyphen, em dash, en dash
		return !/[^\\-\\u2014\\u2013\\s]/.test( item.text() );
	},

The fix was to add a check for dom children.
