merge r11371 from branch 2.2 to trunk
bug 2345 fixed: ability to update the rank of a photo for an existing category. I haven't modified pwg.images.setInfo, I've just added a new method pwg.images.setRank which does this very specific job. git-svn-id: http://piwigo.org/svn/trunk@11372 68402e56-0260-453c-a942-63ccdbb3a9ee
