Export language-specific names

Created by: das-g

While the SELECT INTO queries for layers with common attributes fill in

• name_en
• name_fr
• name_es
• name_de
• name_int

, the VIEWs actually responsible for the export are missing these columns, with exception of the VIEW for the newly added transport_l. (The attributes name and label seem to be consistently exported, though.)

If I remember correctly, these attributes should be exported, too. (If not, they should be removed from the list of 'common attributes' in the documentation.)
