curses/curses_misc.py:

Refactored some ComboBox internals
  Renamed show_first to focus in ComboBox
  Added callback support
curses/netentry_curses.py:
  Renamed NetEntryBase to AdvancedSettingsDialog, and WirelessNetEntry to
    WirelessSettingsDialog
  The "WirelessSettingsDialog" is complete. :-)  Raise it by pressing "C" on a wireless
    network.  Much of the code was taken from netentry.py.  The buttons aren't pretty
    like they are in the Preferences Dialog, but they are fully functional.
curses/prefs_curses.py:
  Refactored to accommodate the ComboBox changes
  Added a warning about changing backends
curses/wicd-curses.py:
  Refactored to accommodate changes to the rest of the program
  Added a constantly displayed message saying how to exit the program, other than
    ctrl+c
curses/TODO: Removed a bunch of stuff that is already implemented, added some stuff that
    needs to be implemented
curses/README: Added/clearified some things
