Greatly enhance the visibility of "Related" in the Explorer

[rtroncy]

Today, the Explorer shows occasionally some relatedness on some pages. For example, the Smell of Cow is Related to Manure. This information is displayed in the top right position of the window, but barely noticed by the users at the moment. We should make it more proeminent!

Next, the relatedness between olfactory objects is, as of now, solely based on the taxonomy defining these concepts. We should make use of our embeddings to display other type of relatedness and do this not only for objects but also for individual smell experiences

We should also consider the vector similarity for Dravniek’s 146 sensory dimensions classification for objects.
According to Mathias Strilic, this would be the appropriate measure to measure similarity between objects.

Correct, this is currently being dealt with in Odeuropa/vocabularies#1

See Odeuropa/vocabularies#7 for relatedness computation
