#10 Show original layout name where you used to show QWERTY

[Chris Morris]

(This feature only makes sense in the context of where I'm going with DVA 2.0 - which will toggle between Dvorak and whichever layout was set originally - we can't always say QWERTY anymore -- but doing this looks to be a bit of work (see System.Windows.Forms.InputLanguage.GetLocalizedKeyboardLayoutName in Reflector) -- so for now, we'll just have an Enabled menu item or somesuch.
