[opensuse-buildservice] [patch] Fix attributes xml for packages

Hi, It looks like the api doesn't output the correct XML for package attributes: namespace and name are not split. For example, I get: <attribute name="OBS:Screenshots"> for a package while I get: <attribute namespace="OBS" name="Screenshots"> for a project. The attached patch is untested but I think it should fix it :-) Cheers, Vincent -- Les gens heureux ne sont pas pressés.
