Folio List: XML save/open added. When Application starts, folio list is not added

so that user gets the option to choose whether he wants to add folio list or not.
Bug remaining:
- When open project file with folio_list present, folio list sheets are at the end,
  not at the beginning.
- Possibly many others. Thorough testing required.
