Replace long scroll behavior with 'scroll to load' concept

[cs1m0n]

I want to have a better UX when navigating through the articles

Right now we are loading the previous 5 and next 10 articles of a chosen article (e.g. from search results). When you search on a specific topic and choose an Hidden Treasure article, the previous/next articles will in most cases have a whole different topic, so it probably does not make sense to continue reading.

The idea is to introduce a 'scroll down/up to load' next/prev article.
