feature 2548 (multiple sizes): adapt the web API method pwg.images.add (used

by pLoader, Digikam, Lightroom, iPhoto), pwg.images.checkFiles (pLoader only).

The "resize" parameter was removed for pwg.images.add since this behavior
becomes the default behavior in Piwigo 2.4.

Just like pwg.images.addSimple, pwg.images.add now uses the add_uploaded_file
function (next step is to merge pwg.images.add and pwg.images.addSimple)
