Warning box when Saving an assignment with 0 points

Problem statement:

At the end of every semester it seems we deal with several instructors who have inadvertently created assignments worth 0 points, and in many cases (except where they chose to display grade as percentage) we have to tell them that they will need to regrade those assignments.

Proposed solution:

Always leave the point value blank when a new assignment is created and don't allow the assignment to be saved without a point value. This would require the instructor to enter a point value (which could be 0) but it would prevent them from unintentionally saving an assignment worth 0 points.
