Bug 9498 - Update encoding for Norwegian sample Z39.50 servers

This patch
- Updates the sample servers installed by the web installer
- Does a database upgrade that changes the encoding for the servers
  in question

To test:
- Do a Norwegian installation and make sure to choose the optional
  sample Z39.50 targets
- Check that encodings for the Norwegian targets (BIBSYS, SAMBOK,
  NORBOK and DEICHMAN) are all set to ISO_6937 (which is the wrong
  encoding)
- Apply this patch and make sure updatadatabase.pl is run
- Check that the encoding for the four targets mentioned above are
  now ISO_8859-1
- Do one search against each target and check that there are no
  "strange" chars in the result list. Searching each of the targets
  for "hessen" should give results that include "norwegian vowels"
- Log on to the MySQL of the test installation and empty the table
  of Z39.50 targets:
  mysql> delete from z3950servers;
- Load this file into MySQL from the command line:
  installer/data/mysql/nb-NO/2-Valgfritt/z3950servers.sql
  and check that it loads without errors and that the four
  Norwegian targets are still set to have encoding = ISO_8859-1
