* gnome/applet/nm-gconf-wso-wpa-psk.c, gnome/applet/nm-gconf-wso.c, gnome/applet/wireless-security-option.c, include/NetworkManager.h, libnm-util/cipher-wpa-psk-hex.c, src/nm-ap-security-wpa-psk.c, libnm-util/cipher-wpa-psk-passphrase.c, src/nm-ap-security.c: Add support for "Automatic" pairwise and group cipher configuration by letting wpa_supplicant handle the details. Add UI elements, new cipher type NM_AUTH_CIPHER_AUTO, and backend support. Works like a charm. Note this does more than add a nice feature, it fixes a bug. Apparently, some people have AP's where the pairwise cipher does not match the group cipher. Insane, but true. git-svn-id: http://svn-archive.gnome.org/svn/NetworkManager/trunk@1407 4912f4e0-d625-0410-9fb7-b9a5a253dbdc
