OpenMW-CS: Add missing icons to UniversalId tables
Currently we only have the icons for referenceable IDs registered. The remaining icons should be added to CSMWorld::UniversalId (except for Type_None which can stay without an icon). Not sure, if we actually have icons for all of these. If some are missing, these should be requests in the appropriate thread in the editor development forum.
A special case to be considered is single ID vs ID table. Do we need separate icons for the later? May require a discussion in the editor development forum.
