Wifi security password screen should have the focus on the password box by default

[Philip Peitsch]

The wifi security password screen shown when attempting to connect to a secured wireless network should have the focus on the password box by default. Currently it defaults to the security type, which in my experience is usually pretty correct. If its focused on the password box, I can simply enter the password and hit enter... rather than needing to tab or mouse through the rest of the screen.
