title: Redux form - how to set fields as touched
body: <p>I'm working with form that consists of multiple pages and I want to solve validation.</p>
  
  <p>When I hit Submit button all fields on the present page shows error messages beneath, but if I change the page then I need to hit submit again because these fields weren't set as touched.</p>
  
  <p>My problem would be solved if I could for example set all fields on the page as touched, once the form has flag <code>anyTouched: true</code>.</p>
  
  <p>I'm using <code>redux-form: '^6.0.0-rc.4'</code> and I have one container where I include redux-form and multiple components consisting of fields.</p>
