As I could see, Localized values are used both for actually localized values, as
well as for passing some constants from C++ side. 
I assume that underscore_style should be used for constants instead of
camelHumpStyle to prevent occasional name clash.

No, it is a JavaScript variable on injection, thus it should follow the variable
naming convention of JS here (like we do for localized strings).

[Denis Kuznetsov (DE-MUC), 2012/03/05 09:25:58]

Done.
