Need to add an option to a lesson where the last problem awards the student 100% if completed.

We don't want to do this on all of the lessons, but on some of the lessons, like the data mining lessons, this was the case. All the other problems awarded full points, but the last one was the only one required. This should be an option because it is sometimes wanted and other times not wanted.

This is done. Checkbox on LessonModify page to make final problem worth full experience.
