add 'last_activity' column to session tokens and delete old ones via a background job
* Add InvalidTokenException * add DefaultTokenMapper and use it to check if a auth token exists * create new token for the browser session if none exists hash stored token; save user agent * encrypt login password when creating the token
Since some apps (ldap et al) still depend on OC_User_Backend this seemed like the cleanest approach.
