solves issue #5 (closed) backup import export

the backup files destination was moved from each apps own fixtures folders to media/backup/vocabulary or media/backup/brick. vocabulary_backup,vocabulary_loadbackup, vocabulary_backup2original, brick_backup, brick_loadbackup scrip had to be adapted.

the running docker container will tar zip and port each night the media/backup folder to /mnt/dockhost. read the docs documentation and Docker file were adapted. cron job for this task have still to be written (issue #4 (closed)).
