Enhance readability of the study docs page
Currently, the documents on the Student Documents page of the AMIV website are displayed in a random order (sorted only by year) given the restrictions of the user (Department, Semester, Subject, Prof, Type). I fear that most of the students (as this is feedback I have received multiple times) do not really find the stuff on the study documents that they are searching. Mostly, because they do not choose the type of document particularly but only the department and subject (yes indeed, students are lazy). Thus I feel that it would constitute a big QoL improvement if the Documents would be sorted by Type all the time (preferably first PVK Material and exams, since that is what most people are searching for, then summaries, lastly exercises and lecture documents). This should allow for a much better readability when not choosing the type directly.
