Custom labels and tooltips for properties in concept view

[joelit]

Reasons for creating this PR

There was a need for renaming property labels in concept view for certain controlled vocabularies (metatietosanasto, kanto) and classifications. These do not strictly follow the normally assumed naming conventions for the concept properties.

Link to relevant issue(s), if any

• Closes New labels for classification concept views #806

Description of the changes in this PR

• Possibility for adding new property labels via config.ttl
• Possibility for adding new tooltips for customized property labels via config.ttl
• Example of the configuration:

    skosmos:propertyLabelOverride

        [ skosmos:property skos:notation ;
          rdfs:label "UDC number"@en, "UDC-numero"@fi, "UDC-nummer"@sv ;

Looks good in general, though I have some concerns in the comment.
I will see if I can fix those and then test to see if this can be merged.

This isn't relevant to the PR, but OK, it's a valid docstring fix.
