Feature Request: actionInput template helper function

[AugustMiller]

Description

It'd be lovely to be able to generate the hidden input element for form actions… We already have shortcuts for csrfInput() and redirectInput(), so this feels like a handy addition.

Effectively, thinking something like this:

    // new \Twig_SimpleFunction('actionInput', [$this, 'actionInputFunction'])

    // ...

    /**
     * Returns an action input wrapped in a \Twig_Markup object.
     *
     * @return \Twig_Markup|null
     */
    public function actionInputFunction($actionPath)
    {
        return TemplateHelper::raw('<input type="hidden" name="action" value="' . $actionPath . '">');
    }

(I wasn't sure whether the name of the field depends on the actionTrigger setting?)

Happy to issue a PR—but wanted to make sure I wasn't missing something that's already available!

Sure, we’d accept the PR. docs/dev/functions.md would need to be updated as well.

Nope, that only applies to query string action params.
