Prevent storing unnecessary extra data

[kbuffardi]

The application is storing more information than is necessary. In particular, when the user enters DONE it is currently saving that as the last item in the list. When it prints out the list, it prints out everything besides the last item.

This is a sloppy solution.

Let's fix how we handle it so that:

• When the user enters DONE that value is NOT added to the list of favorites
• When printing the list of favorites, print the entire list
