* M6: pasted layers keep the colours of their shared paint styles (#1638)
A clipboard links a style by the guid it has in its library, which it doesn't hold, and by its library asset, whose copy it does hold. Mapper::resource_id now takes a guid only when the file holds a node by it, else the asset, so .fig import and paste agree; a link to a style that really isn't there keeps the layer's stored colours, with a note.
* M6: Swedish catalog: keep both new import notes after the merge
