Add an updated version of context.json #153

[Ludee]

Summary of the discussion

I copied the context.json from version 1.6.0.
I sorted the imported ontologies and harmonised with the imports of the oeo.
Only a few keys are already included. This is a large follow-up to find suitable terms in existing ontologies or adding them to the oeo.
