Group and Sort Exercises in Course Dashboard about artemis

Currently, exercises are grouped by type. However, I think an option to switch to a time-linear view would also be handy in some cases; maybe add an option to switch views where all exercises are ordered by release date/due date and grouped by week instead of their types?

@krusche There are still a lot of places where ordering is not implemented. It's getting really inconvenient to find an exercise, e.g. the default sorting by exercise type in the tutor dashboard is absolutely useless. Also as a user, I don't understand why H02E01..., H01E02, H01E03, H01E04, H01E01 is a meaningful order.

Please fix this, it shouldn't be something hard to do but helps a lot for everyday users like tutors.

@Khalphion we will fix the order in the tutor course dashboard and also make sure the option show finished exercises works
