/**
 * preferences class used for setting application preferences
 *
 * preferences are read into following arrays:
 * - $data effective prefs used everywhere in EGroupware
 * Effective prefs are merged together in following precedence from:
 * - $forced forced preferences set by the admin, they take precedence over user or default prefs
 * - $session temporary prefs eg. language set on login just for session
 * - $user the stored user prefs, only used for manipulating and storeing the user prefs
 * - $group the stored prefs of all group-memberships of current user, can NOT be deleted or stored directly!
 * - $default the default preferences, always used when the user has no own preference set
 *
 * To update the prefs of a certain group, not just the primary group of the user, you have to
 * create a new instance of preferences class, with the given id of the group. This takes into
 * account the offset of DEFAULT_ID, we are using currently for groups (as -1, and -2) are already
 * taken!
 *
 * Preferences get now json-encoded and no longer PHP serialized and addslashed,
 * thought they only change when they get updated.
