Subject: setup2hd: major changes

- use $DIALOG instead of calling dialog; hopefully we can use Xdialog
  at some time
- warn user if terminal is too small to display fdisk/gdisk interfaces
- improve installation time of squashfs modules to harddisk with a factor 6,
  by using a different way to show progress
- tweak dialogs so that they show less empty space
- if possible, set sane default selections in menu's to make the installation
  process smoother
- fix many small bugs in user account creation, password dialog, user config
  extraction, removal of redundant configuration questions etc
