Restore the file object properly

This took a a damn long time to debug :(

Well due to possibly and bug back in filefield or cck, the file saved in the cck cache for that field is not complete, its only partially ( e.g. missing filename ). This means when the cache is used to load the values, swfupload fails to initate the file-list.

As in the patch, we need to ue the load method of filefield to restore the object properly. e.g. this is also done in imagefield to make it work .. without any further comment on why... :/
