Create Larger Test Use Case Scenarios

[tomca32]

We have a decent amount of feature tests which test a lot of features in isolation by automating the browser. We should create some more complex test cases that portray real application usage and not limit themselves to one feature.
It would be good if some of these scenarios would come from people who actually use the application on a regular basis.

One example of what we would like:

1. Log in as a super admin
2. Create a new organization
3. Create new subject and skills with grades
4. Add a user to new organization with admin role
5. Have the new user log in and add chapter, group, and a bunch of students

This tests large parts of the application and would be helpful in diagnosing when something goes wrong. One thing we must be careful of is to make these kinds of tests very reliable otherwise we will end up with a flaky test that everybody ignores when it fails.
