Early submission bonuses

[oseppala]

A-plus once had a way of granting early submission bonuses. The remnants of this feature are still visible in the CourseModule model here:

There has been discussion about introducing the feature back to give students a incentive to submit exercises early. As the feature does not affect late submissions it should not affect deadline calculations and should be fairly straightforward to implement.

There are however a number of different ways this could work.

• There could be one bonus deadline with a fixed bonus
• There could be a bonus deadline with a bonus that linearly goes to zero
• There could be a bonus deadline with a bonus that goes down in specified steps

The last and first option are the same if there is only one step

This is a feature request. Comments are welcome
