Introduction of a new device class (localhome).

- user-home is on local disk
- additional entry in dolphin: home@server
- display info about localhome on login-screen
- provide unison-config for sync home with home@server
- force user to be logged out immediately after first login, because
  home-dir must exists for bind-mounts on /lmn/media
