[FEATURE] New task "journey" design

[esmeetewinkel]

What? Display component that displays a list of tasks (which may themselves be task groups) as a route connecting dots.

Why? This design would evoke the feeling of being on a learning journey. Inspired by other learning app designs.

How?

• Screen divided into two columns, design needs to scale sensibly also when long text strings are provided as titles
• Each task can have different statuses which will have minor effects on the way it is displayed (such as completed, locked)
