[Click] Simple Authenticator:"Click" element Class

[John Bicket]

Hi Guarav,

SimpleAuthenticator is a click element in the elements/wifi/ap
directory. You probably don't want to be using it with a wlan device, 
it only really works with Atheros based chipsets.

I am currently working on a howto for building a roofnet configuration,
I will be done in a day or two and will post it.
