LIBRARY: menu.php - a few classes for managing menus
HISTORY:
 2009-08-09 Extracted from SpecialVbzAdmin.php
 2009-11-04 clsArgs
 2010-02-20 clsWikiSection::SectionAdd(), ::ToggleAdd()
 2010-04-06 
   * General reconciliation with edited non-dev version
   * Done earlier but not logged here:
     clsWikiSection::ArgsToAdd() (ported from other copy of menu.php)
     clsAdminTable, clsAdminData, clsAdminData_Logged, clsAdminEvents, clsAdminEvent
 2010-10-06
   Reconciling with dev:
   * Minor improvements; split() is deprecated; small bugfixes
 2010-10-07 reconstructed clsDataSet::_AdminLink(), which apparently got lost during reconciliation
