From faa543851ba9fc25ffb0d25a7876d4486757f21a Mon Sep 17 00:00:00 2001
From: plegall <plg@piwigo.org>
Date: Fri, 17 Oct 2008 20:39:30 +0000
Subject: merge -c2754 from branch 2.0 to trunk

new: upgrade script from 1.7.0. Instead of previous upgrade scripts, I call
directly the "unit" upgrades from 61 to current. Previous upgrades not in
the database are inserted but not applied (and have an explicit description
saying so).
