Force shipping for virtual / weightless items

Hi,

There is no mechanism to remove a step. That's because the system doesn't what is in each step unless it displays it, and it only displays the current step.
However, there is a mechanism to automatically skip empty steps.
It is implemented for the "login" view from example. If you're already logged in, and you login have the login view alone on a step, if you try to access that step, it will automatically redirect you to the next one.
However, that mechanism hasn't been implemented for the shipping view. To do that, add the code:

public function haveEmptyContent(&$controller, &$params) {
		$checkoutHelper = hikashopCheckoutHelper::get();
		if(!$checkoutHelper->isShipping())
			return true;
		return false;
	}

public function validate(&$controller, &$params, $data = array()) {
