Support for multiple submissions

[dopefishh]

If an assignment allows multiple submissions, the zip file contains multiple submissions by the same user. I propose to add a method to throw away the old submissions because in most cases you will only grade the last.

The identification number and the name stay the same. Only the date part is different.

Possible solutions:

• Flag in verdeel.sh that defines it for the course that propagates to bsunzip.sh
• Helper script sent to the grader so that they can choose whether to run it
• ...

I think a "combine.sh" script or somesuch is a good solution, and then run it by default in verdeel.sh. Probably you want to do combine before randomly sorting the workload.

If we want to be really fancy, this script could create a git repository and store the previous submissions as a submission history (instead of throwing them away)?
