[Improvement] Focus inputs when tapping the label

[markusguenther]

At the moment it can be annoying to get the input to be focused.

So it would be nice if you can tab the label or form group and then automatically focus the input.

I could be wrong, but don't you just need to do the following in createInputCreator.js?

Before:

<Label>{ label }</Label>
{ renderComponent(props) }

After:

<Label>{ label }
  { renderComponent(props) }
</Label>
