/**
* 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.
