get BoredAPI working for the activity type chosen by User

We discovered that the Bored API doesn't always suggest activities that can be done online, but also lots of offline ones, e.g. "Learn how to play a new sport", "Learn how to fold a paper crane", "Learn a new recipe" etc.

Swapnil had the great suggestion that if this is the case, we could give the user the choice:

• get away from your screen and do the thing
• watch someone else do it on youtube

If they choose the second option, we somehow pipe the activity description from BoredAPI into the search terms for the YouTube API...

on the feature/test-boring-app branch, i got the demo button to push a random activity into a demo card.
