Localization

[andgineer]

It would be nice to have localization option.
I'd localized hbs files for Russian language, but it would be better to have that as command line switch, not as a fork like I done now.

I was thinking about this a couple of months ago, and I had some ideas, but never the leisure to get working on it.

At the moment, some of the labels are part of the styling in the Less files. It seemd to me like a good way back then, but now I think it would better to do it another way.
Maybe a special helper that resolves message keys.

I guess it would be an extension to customize-engine-handlebars
