Tutorial prompts for sound asset unnecessarily

[brian-swan]

This tutorial requires that a user add a sound that is included as part of the script: http://tdev.ly/knzbqxul
However, the tutorial engine prompts the user to search for a sound. It should prompt the user to use the sound that is available as part of the script (see screenshot).

By default, the tutorial engine always prompt the user for art resources. It allows users to customize the pic/sounds while keeping the same gameplay.

In general, we could prepopulate the search with the art resources already available in the script so it the user can select easily.

OK. I can live with this, but (from a teaching point of view) it raises the priority of #15 . That one is high priority for the work I'm doing now. It affects multiple tutorials.
