Add NEXT button in between messages in introduction block?

[fagiothree]

In the know_roles module, could we add a NEXT button to the first message, because the first two messages are both very long. It may be easier to read if we separate them.

The only way to achieve this would be to add a NEXT button after every message in the introduction block (instead of just after the last). Need to check with Zuyi if she's happy with this solution

Zuyi agreed not to make any changes
