Added more PICA libraries

I added some more PICA libraries, including three of the four you listed as past requests:

- TIB/UB Hannover
- UB Osnabrück
- Hamburg (all on the same server, using different databases):
 - Campuskatalog
 - Behördenbibliotheken
 - Gerichtsbibliotheken
 - Hochschulinformations- und Bibliotheksservice der HAW
 - Hochschule für bildende Künste
 - Hochschule für Musik und Theater
 - Lehrerbibliothek
 - Museen
 - Polizei
 - Staatsarchiv

They seem to work quite well, but I didn't test all the different search query types on all libraries.

I didn't have the time to add Darmstadt UB, because it uses different IDs for the search queries and i haven't found a way to get a permalink to one book as it is possible in the other PICA systems.

I don't know if there are encoding issues again in the JSON files I created, I simply copied the Kiel file and edited it in Eclipse.
