+    Export nm_vpn_editor_factory_vpnc properly
+    
+    - commit e2fc231149165cb37a25362b85cbcd58b15a2a11 removed
+      libnm-glib version
+    - after that commit, nm_vpn_editor_factory_vpnc was not correctly
+      exported anymore which caused the settings editor be missing
+      when adding or editing a vnpc connection in gnome-control-center
+    - this commit re-adds the removed G_MODULE_EXPORT declaration
