Bug 4041: Second Step: Add system preference and "German style" address formats for staff

To test:

Apply patch
Do a database update (e.g. by changing version number in kohaversion.pl)
Find new system preference 'addressformat' in I18N/L10N
Choose 'German style'
Go to Patrons and edit a patron / create new patron
Verify that Zip code appears above City
Change system preference to 'US style'
Verify that Zip code appears between State and Country.

BTW: New formats can be added by editing i18n_l10n.pref (add a new code, e.g. fr for "French style") and copy / modify the includes using the same code as postfix.
