Page title for swissbib baselbern and jusbib

[liowalter]

Currently, swissbib baselbern and jusbib page titles start with "swissbib : " https://baselbern.swissbib.ch/Record/507714814 https://jus.swissbib.ch/Record/507714814

We should adapt and replace swissbib by "swissbib Basel Bern" and "jusbib"

Proposed solution :

• create new configKey viewSpecificTitleString (or use das "title" configKey?)
• use that key in the templates
