Logged in as <username> gets wrapped

This was already reported in #975506: "Logged in as [username]" in authorize div gets wrapped but doesn't appear to be actually fixed.

The problem is still there in the latest Danland 7.0 when using Chrome 11.0 and is fixed by the following addition to style.css although I'm not sure if that's the best way to be handling it.

#authorize ul li { 
white-space:nowrap;
}
