Not getting properly the Boolean value of the qualifiedTableNames property

I started working again with this wonderful plugin and I realized that the qualifiedTableNames property value was not setting properly because it is a boolean value.

I did not have time to check the orderTables property but it could happen the same.

When I was getting the property value and the invoking the method toString it was returnin the whole datasource configuration. Now with this fix it is returning just the boolean value.

Thanks
