When adding a new material to the content library user assets, all of the used modules should be moved.

If there are some bundles, they should be moved as content library as well.

The module names should be corrected for bundles. E.g. when the exported item is a Generated.Bundles.Materials, it should be changed to Generated.Bundles.UserMaterials.

Also the extraction process should take care of adding the basic material to qmldir file in order to be recognized as the correct module.
