add has-economic-value #958

closes #958

As it was easier to do it myself than to explain, I added domain, range and inverse for the new object properties.

Additionally:
In the current implementation, the hierarchies do not match. The the label implies a connection to CO2, but the definition doesn't. Seeing now all classes connected, it makes more sense to me if we:

1. Relabel social cost of carbon to social cost of emission and update the definition to: Social cost of emission is the cost the society bears for an emission value.
2. Include new subclass social cost of carbon emission: Social cost of carbon emission is the social cost of emission that the society bears for an greenhouse gas emission value.

And while thinking again, is this really a costs of process attributes? Or are these in fact costs of the processes themselves?

I'll open a seperate issue for this: #1036.

This should be 'economic value of' some 'greenhouse gas emission value'

This requires moving a bunch of classes to oeo-shared. Let's wait for #1036 here, to see what really needs to be moved.

Ok.
