[Apc-aa-coders] CVS changes

[<jak...@se...>]

04/05/03 - enhanced the view types definitions in constant.php3 so that
(jakub)    help text may be added and field type overrided (used in Alerts
Selection Set view)
         - enhanced zids->add() to work with arrays and zids objects
         - added zids->union() and made some minor fixes in zids
         - added a new setting to Alerts Selection Set view, to choose
           whether the corresponding filters should be grouped by selections
           (see doc/reader.html for a description)
         - fixed Alerts manual sending: all collections were sent instead of
           only the current one
         - added mutual exclusion to reader management usernames and AA
           permissions usernames (the same username can't be used in both)
         - separated Alerts doc to doc/alerts.xml and enhanced it
