WEP connections created in Sugar always use open authentication

[greenfeld]

1. Configure an AP to support a WEP hexadecimal key, 128-bit, in 802.11 b/g (no "n") mode with WEP forced to "closed" or "shared" authentication.
2. Attempt to connect to this AP from Sugar, giving the same hexadecimal key and choosing "shared" authentication.
3. The connection attempt will fail. Depending on the wireless card model you may see entries in /var/log/messages stating that the association handshake failed.
4. Switch to GNOME and view the Wifi connection settings in nm-connection-editor. The connection will have been created with open authentication.
5. Change the connection to "shared" WEP authentication in GNOME and save the settings. Attempt to connect to the AP in GNOME and now the connection will work.

GNOME's password entry dialog for a WEP AP never asks for the key entry mode or WEP type, so perhaps some configuration logic has been removed or is presumed behind-the-scenes.

Seen in OLPC 13.1.0 os24/os26 on more than one XO model/wireless card.
