Contacts: small merge cleanups

apps/contacts/README.tanghus

-As I like to run regular, automated backups of my PIM data I looked into an 
-easy way of getting the direct link to an address book, and noticed the 
-elegant way it was possible in the calendar, where you can click on the 
-'Calendars' button and download it directly.
-I modified the export.php script for the contacts app and can now run backups 
-with wget and http authentication. Hence the name 'tanghus_remote_backup' for
-this branch.
-Then I implemented the nice popup window function to get an UI for it and one 
-thing lead to another: 
-
-As for the Calendar app there's a js popup for address book activation, CardDAV link, export, 
-edit, delete and add address books.
-
-When making changes to the address books the contact list is updated to show the
-contacts in the active address book(s).
-
-When an address book is activated the setting is saved using OC_Preferences::setValue().
-
-Most of the code is copy/paste from the Calendar and Contacts apps ;-)
-
-Tested with fresh clone from git@gitorious.org:~tanghus/owncloud/tanghus-owncloud.git, removed
-database and config.php.
