Hi kordero,
thanks for review. I'm in process of removeing most of those classes.
But `.system-remove`, `.system-title`, `.system-placeholder-wrapper` and `.system-wrapper` are used in JavaSctrip (for dynamic add/remove of forms) and I think that change in DOM structure should not change behavior of page. So if you agree I'll keep those four classes.
