Summary:
Implement DAV folder sharing based on draft-pot-webdav-resource-sharing standard
We keep the DAV ACL standard implementation as an option, but this standard
does not cover the folder discovery, so we'll not use it with Kolab setups.

Extends existing functionality that worked in kolab plugins' UI
in a way that:
- ldap lookups are optionally cached
- replacing is done also in Mail/Settings parts of the UI
- object_prettyname() uses the same technique as folders listings
- store and compare the number of objects stored after last sync
- use a (configurable) refresh interval and periodically force re-sync
ATTENTION: requires database schema updates
