Switch Case support for Actions

[smaugho]

Actions should support Switch-Case structures, right now this should be done:

 if (optionFragment == 2) {
                $SearchWhereFragment().searchOption(searchOption);
            } else {
                if (optionFragment == 3) {
                    $SearchWhenFragment().searchOption(searchOption);
                } else {
                    if (optionFragment == 4) {
                        $SearchWhoFragment().searchOption(searchOption);
                    } else {
                        if (optionFragment == 5) {
                            $SearchResultFragment().searchOption(searchOption);
                        }
                    }
                }
            }

This is the only way to handle this kind of situation with current actions.
