Filesystem restructure after git removal
Depends on dtu-enote#85
Quiz and website should have all their files in
vol/xxxxx/{pages,quizzes,uploads,sharelatex-{private,public,backups}}
sharelatex-private : enotes are built here
sharelatex-public : enotes are moved to here to appear in the menu
sharelatex-backups : nightly dumps made by your backup script
