På Vei - Input Focus Improvements

This is a small extension that improves the input focus behaviour in lessons on the På Vei website.

Improvements

• When opening a lesson, the input focus is set to the first input field.
• Pressing the Enter key in a lesson is the same as clicking the Neste button, unless a button is focused.
• When a lesson is completed, the Prøv igjen button is focused if the lesson is failed, and the Neste button is focused if the lesson is passed.
  • If the Prøv igjen button is pressed, the input focus is set to the first input field.
  • If the Neste button is pressed, the input focus is set to the first input field in the next lesson.
  • If the lesson is the last lesson in the chapter, the input focus is set to the Neste or Oppsummering button in the chapter navigation.
