- add field {fs_type} partially replacing {pt_type}

  {pt_type} is always a number, {fs_type} is always a string
- introduce set_isFormatted()
  (to ensure {notFormatted} but also {fs_type_from_magic} and {bad_fs_type_magic} are updated)
- don't use 0x483 for ext3 anymore (same for reiserfs...),
  the type_name gives both a pt_type and a fs_type

- many accessors from partition_table removed (type2fs(), fs2pt_type())
- remove isThisFs() (not useful anymore since we can use directly {fs_type})
- remove isFat() (inline the function)
- other isXXX() from partition_table are moved to fs::type
- part2name() is now fs::type::part2type_name
- name2pt_type() is now fs::type::type_name2subpart()
- partition_table::important_types() is now fs::type::type_names()
- fsedit::typeOfPart() is now fs::type::fs_type_from_magic()

- no need to truncate type_name since they are shorter
