prüfung/notenimport enabled per config + adapt notenliste.xls.php highlighting as per config; check if higher antritt prüfungen exist when editing existing ones (changing grades is not allowed, dates inbetween the other 2 antritt termine allowed); prüfungstermine with entschuldigt note are being preserved since the whole series can have 1max; frozen columns selection dropdown + 4 columns freezable (selector, uid, vorname, nachname) -> setting saved in local storage; better mirroring of new pruefung studenten dropdown with actual table sort + update the label there to be uid + name aswell; fixed the note_vorschlag select input cell; table sort doesnt clear selection; show the NotenlisteLinks.js in import modal and filter it based on LE selection;
