Thomas Bruederli af6d366a1f Optimize access to kolab contacts using a sorted and limited query (#2828)
- Add columns for sorting in kolab_cache_contact
- Extend bin/modcache.sh script to update existing cache records
- Add setters for ORDER BY and LIMIT clauses
- Adapt the kolab_addressbook plugin to fetch contacts page-wise

ATTENTION: This changeset contains database schema changes!
Run `bin/updatedb.sh --dir plugins/libkolab/SQL --package libkolab`

Afterwards, the cached data needs to be updated. To do so, either run
  `plugins/libkolab/bin/modcache.sh update --type=contact`
or execute the following query
  DELETE FROM `kolab_folders` WHERE `type`='contact';
