    Add option to jump directly to only record.

- Fixed hidden filters for initial search made in somewhere else than Search/Home.
- Fixed lateral links (author, subject etc.) to also include the current hidden filters.

* truncate metadata values according to column data type definition (avoid fatal error in strict database mode)
* extend varchar datatype to 255 chars for columns resource.title and resource.author (maximize allowable text)

Added words voor 3.0 release

Escaping bug getting PrimoCentral records

- It is optional configuration specifying the path to the drivers configurations relative to vufind config dir -- omit to locate those in vufind config dir -- it also could be an absolute path

- (e.g. Primo uses tlevel for both 'available online' and 'peer reviewed').
- Added better support for checkbox facets in search history.
