Display relative percentage of achieved points on view_points

[alyaeanyx]

Currently, the view_points page only displays the "total achieved points / total achievable points" percentage in the "Punkte" section. Personally, I found this to be inconvenient when comparing my points with the exam admission threshold because the points of exercise sheets that are not yet released or corrected are included in the number of total achievable points.

This PR adds a second percentage, namely "total achieved points / total achievable points of already graded exercise sheets" and displays it next to the other percentage in a way similar to the Übungsgruppenverwaltungssystem of the Faculty of Physics and Astronomy. This percentage is shown iff there are ungraded sheets.

Thanks for your suggestions! :smile: I've fixed the divide by zero issue and improved the code style in models.py.

Oops, you're absolutely right, I forgot to stage models.py for the commit :sweat_smile:

@alyaeanyx On an other note: MÜSLI is looking for a new maintainer beginning January. If you are interested, send me a message :) (That's a 20h HiWi position)

Haha, sounds great, but I think I don't really have the time for that because of my studies :sweat_smile:
