NetworkManager, ASUS led

[Howard Chu <hyc symas com>]

Following up on this thread

KDE's kwifimanager was explicitly patched to toggle the Wireless LED on/off on 
Asus notebooks. It seems that the function really belongs in NetworkManager 
instead. I patched my copy of NetworkManager 0.6.5 to add the function, the 
patch is attached. It's probably not the cleanest approach, but it works for me.
