module.config:
configuration of VuFind core was refactored in major parts
-> this was the reason our own RecordDriver SbSolrMarc wasn't instantiated anymore

SbSolrMarc:
only some adaptations for test purposes (work to be done by Oliver)

RecordController / SearchController / Results have been deleted because they aren't necessary anymore with the new
VuFind Plugin Architecture (were created in the course of the last year)
