Yet another checkpoint in building the Preferences Dialog up to completion. Some of the code isn't used yet, but this should all be done relatively soon.

curses/curses_misc.py:
  Added a function in the ToggleEdit to set its text to something
  Changed the name of ComboText to ComboBox
  Provided the ability to generate the initial parts of a ComboBox w/o needing the screen.
  Added ComboBoxException, a simple derived exception for the ComboBox.  Used it to die of the user never called build_combobox()
curses/prefs_curses.py:
  Changed the names of some of the widgets.
  Adjusted the code to use the modified ComboBox widget
curses/wicd-curses.py:
  Adjusted the code to use the modified ComboBox widget
