Distinguish domain ontology concepts vs. YSO concepts in hierarchy display

[tpalonen]

Several Finto customer organizations have requested that domain ontology concepts should be distinguishable from YSO concepts when browsing a domain ontology's hierarchy in Finto. Either visually (coloring) or by exluding irrelevant YSO concepts in hierarchy visualization altogether. Some organizations, when giving training to library customers in information retrieval, are known to not recommend Finto because of this feature. Needless to say, this is a critical issue.

Closely related to issue #19.

In practice, this would require

• adding concept type information to the result of the REST hierarchy method (which will make it slower)
• using the type information to color concepts in the hierarchy display An open question is how this should be configured in vocabularies.ttl.

Or alternatively, I'd prefer implementing this by first adding import support (#63) and then

• adding information to the hierarchy method results about which concepts are imported
• using that information to color concepts in the hierarchy display This is more straightforward to configure, because the distinction is between imported and non-imported concepts instead of different concept types (of which there may be many in a vocabulary).

implement with finto-specific javascript

Now this has been implemented in Skosmos code. I think the code to implement this should instead go to a local JS file, for example by adding JS code to the local footer.inc. I would prefer not to have hacks like this in Skosmos code.
