merge r4444 from branch 2.0 to trunk

feature 1312 added: pwg.images.setInfo can replace multiple values propreties
(tags/categories). The primary condition is to provide "tag_ids" and/or
"categories" input parameters, ie pwg.images.set won't create emptiness. You
can reduce the set of tags/categories but not remove all tags/categories.

bug 1277 fixed: with a stronger algorithm for adding/replacing categories, we
now avoid to recreate an existing image_category association.

When a remote client calls pwg.images.setInfo, Piwigo returns an error 500 if:
1. the "categories" parameter is malformed (no numeric id inside)
2. one of the input categories does not exist at database level.
