feat(links): Visited links update - OEL-1737

[planctus]

It seemed easier to do, i had doubts this could be done at some point. instead. The specifications regarding the styles that can be associated to a :visited link do not seem entirely consistent between different browser, their "privacy" policy it's basically preventing fancy style changes. It seems it is possible to fulfill the requirements, though, and i hope the current styles are doing that. There was a flaw i think in the definition of the "default" links, the :not were not chained and therefore the styles were also being applied to the standalone variant.
