Tried to fix the now non-functioning back and forward buttons and the "second click to display previous" feature but so far failed. This happened after two major refactorings - of the SCSS to unify shared features under _shared.scss and the S to S2 state storage in _status_and_enums.js.

I'll continue with additional features now and will revisit this later. To compare with working version load the head of the branch called EndOfSaturday.
