Hardware fixes: issue version, installer Cyrillic, console TUIs (0.9.2)

- /etc/issue shows the Das OS version instead of the kernel's; the server
  installer carries it into the installed system.
- das-server-installer: setfont -C /dev/tty0 before the language menu
  (sudo runs it in its own pty, so the Cyrillic was drawn as Latin), and
  floppy drives are no longer offered as install targets.
- ncdu on the desktop image and in das-server 0.4.0.
- das-shell 0.2.0: each prompt line sets its own color; the dbanner start
  screen buttons are no longer covered by the key bar; on the Linux
  console (TERM=linux) dprompt and dbanner draw solid borders and swap
  the glyphs that no console font has (▊▎▔▁ and others) for ones it has.
