Xsl utility / Add a function to retrieve thesaurus title with its key

[fxprunayre]

Some schema (eg. DCAT) does not contain thesaurus name in the metadata record. While indexing we add the thesaurus title in the index. This utility function allows to retrieve it with the thesaurus key (eg. external.theme.publisher-type).
