Add links to salamanca.school in Wikipedia

[dvglc]

Not really to be achieved in the web application itself, but it would be nice (wrt visibility, public science, etc.) to have links in Wikipedia articles on the school of Salamanca – at least in the Spanish, English, and German version – to the project (i.e., to salamanca.school), given that stability and performance issues with the web application are resolved:

• https://es.wikipedia.org/wiki/Escuela_de_Salamanca
• https://en.wikipedia.org/wiki/School_of_Salamanca
• https://de.wikipedia.org/wiki/Schule_von_Salamanca
