* eGroupWare API: VFS - Hooks to add/rename/delete user and group home-directories

* - create the homedir if a new user gets created
* - rename the homedir if the user-name changes
* - delete the homedir or copy its content to an other users homedir, if a user gets deleted
* --> these hooks are registered via phpgwapi/setup/setup.inc.php and called by the admin app
