Skip irrelevant schemes for subject headings and genre/form terms

Genre/form terms from YSA, MARC and MeSH are irrelevant, so hide those.
Subject headings from LCSH seem to be mostly irrelevant too.

We can utilize SPARQL to determine which term schemes are occurring.

At the time of writing, I have changed from skipping only MARC to skipping all except QLIT, SAO(GF) and Barn(GF). One false negative is the scheme-less person subjects, e.g. for "Charlotta Lugn" and "Shirin Sundin" for Stenhjärtat.
