[Speedgrader] Button for 'Points actualization' fixed in the beginning

Problem statement:

When grading the tests of courses with a big number of students, teacher must go to the end of the page after each grade set, in order to save and conclude the correction.

Proposed solution:

It would be easier and faster if the button to confirm and save the grading where fixed on the top of the page or beside the button to 'Send' a comment, which is fixed on the right side of the screen. For a course with just a few students is easy to conclude the grading, but if the class has over more than a hundred students to be graded, and the teacher has to scroll from the top to the bottom of the page in each student, it takes a lot of time to finish the process, which would be much better if teachers could just type the grade and click the button in a visible place on the screen, without scrolling in each evaluation.
