curses/curses_misc.py: ADDED. Various urwid classes that I use throughout the program.

curses/prefs_curses.py: Frontend is complete.  However, it is still missing buttons and the ability to save information.  Removed code that is now in curses_misc.py.
curses/wicd-curses.py: Removed code that is now in curses_misc.py.  Tweaked the visuals a little bit.
curses/README: Preferences configuration is a WIP now.
curses/TODO: A combo box has been implemented in curses_misc.py, so that part has been removed.  Also added a part about making a man page.
