[development] drop tasks for Drupal students

[Brad Bowman]

Another really great opportunity here is in writing documentation. We
often complain that we can't look at Drupal with fresh eyes, which
makes it difficult to write quick start guides/documentation geared
towards newer users, since we've forgotten the issues we struggled
with initially. It'd be great to leverage all these new perspectives
to get some more documentation geared towards entry level users
written.
