Avoid use of using.

This is being used 216 times in just the chrome/browser/ui directory structure,
so I assumed this was an accept pattern.

why is this here and not in retail_mode_screen_locker.cc

[rkc, 2012/02/08 02:52:19]

Seemed like a better fit since all the UI display code is here. Moved anyhow, it
fits with that code too since the declarations are there.

Done.
