ah ok, so name() would return the filename, whereas layerName() would
return the filename without extension, to be used in the drag&drop
operations. Sounds reasonable.
Would need to modify mime data stuff also, in QgsMimeDataUtils::Uri
what about file-based datacollection items? I guess only the layers
can get dropped to other targets, therefore no need to change
