Changing the question from single spaced to double

[MasterOfGoats]

I added the line
line-height: 2.0;
to .questionDescription in QuestionPanel.css to adjust the spacing between lines from single space to double space.

Nice start. I tested it and there is line spacing.

However, there is more to the task as outlined in issue #86
For example, the question description does not preserve line breaks, but you can do that with the CSS line white-space: pre-wrap; in web/src/components/question/QuestionPanel.css in the class .questionDescription. The assignment description should also have line breaks and line spacing.
Also, you need to change the TextAreas for the Assignment and Question description so that they grow as the text becomes longer. I outlined how to do that in issue #86
