Fix to make the Unlock mechanism of WebDAV work. Previously when using unlock in cadaver etc was used the lock entry corresponding to the file was not deleted in the sqlite database table oc_locks. The error was because the delete query in the Unlock function was not getting executed :)

this fixes incorect generated links in some cases

Currently all users can set one OpenID identity that allows access to the account.

The identity url's for the server is owncloud/apps/user_openid/user.php/$username

Move documented functions for reference into OC_USER_EXAMPLE class.

keeping tracked of the logged in user is no longer done by the active backend but by oc_user directly instead

multiply backends can be active at the same time, allowing alternative authentication procedures like openid or tokens to be used next to the regular user system
