- update_global_rank new function : far more intelligent update. Take into
account the possiblity to have category tree not in category id ascending order - update global_rank when moving categories among the same parent - new function mass_updates : depending on MySQL version, create a temporary table, make one big insert and one big update by joining 2 tables (4.0.4 or above) or make 1 update per primary key - function update_category improved for representative_picture_id check : only one useful query (equivalent to NOT EXISTS) instead of N (N = number of categories) queries git-svn-id: http://piwigo.org/svn/trunk@625 68402e56-0260-453c-a942-63ccdbb3a9ee
