curses/prefs_curses.py: Adapted widgets for integration into the main UI

curses/curses_misc.py:
  Removed the "bottom_part" from the TabColumns
curses/wicd-curses.py:
  Added support for editing preferences directly in the main UI w/o a dialog
  'left' now only quits with saving for the NetworkSettingsDialogs
    (suggestions as for what to do here would be appreciated)
