meta+left/right now sets focus back to whereever you were in the list. curses/wicd-curses.py: Made a custom combobox for the wired networks. The one during the last commit was actually the wireless list. (Hopefully) made the wired network show up when it is actually active. Removed appGUI.call_connect and appGUI.connect. They are no longer needed. in/man=wicd-curses.8.in: ADDED. wicd-curses(8) man page setup.py: Install the above man page if we are installing the rest of the curses client
