typo
clean up no0b mess made with batch and student routes. eg. load list of students on show batch.
smaller side bar
fix current batches definition
removed students#index (used show batch instead)
batches: load current schoolyear on controller
fetch faculties on controller
delete unused functions in grades controller
temporary mediocre unforgivable fix for PE final grade. MUST refactor.
Merge branch 'refactor'
