Added record normalization to preview service.
MARC: Added publishDateSort, added 110 to authors in merged component parts, removed original MARC UNICODE normalization and fixed getSubfieldsArray to work properly when subfield code is 0.
LIDO: Added alt titles for other languages.
Removed the iconv transliteration tweak as it didn't work properly even though it was faster than mb_strtolower.
NdlLido: support alt titles.
NdlMarcRecord: Use mb_strtolower instead of strtolower. Extract first publish date to main_date_str properly.
SolrUpdater: Don't try to access db if it's not opened (Preview). Don't normalize UNICODE of fullrecord field.
Added ending line feed.
