Title: Add multiple fields sorting

Feature, which allowed sort by multiple fields e.g.
You have two field in your database (last_name and first_name), but in form you have one field called 'name', which is concatenation of two fields from db and you have to sort by last_name firstly and first_name if the last_names are the same.
So now you can do it in simply way.
