Implemented the "browsable" storage logic.

                data = {'data':[]}

                # Get storages

                storages = list(Storage.objects.filter(group=None)) + list(Storage.objects.filter(group__user=request.user))

                storages = list(Storage.objects.filter(group=None,browsable=True)) + list(Storage.objects.filter(group__user=request.user,browsable=True))

                # Oder storages (re-orderded in the file manager anyway)

                storages.sort(key=lambda storage: storage.id)
