file format
- show error message when trying to open a .zip file that doen't contain
the expected files of a Samsung J series or Toshiba .zip channel list
- show error message when trying to open a broken .zip file, which is
most likely caused by exporting to a USB stick formatted with NTFS
- allow changing the "crypt" flag for Samsung .scm lists
- iterating through loaders supporting a file extension till one can read the file
"hidden" and "skipped/unselectable"
- reference lists: the satellite orbital position is no longer used
to match channels. (Samsung J series does not provide that info).
- Samsung J series: favorite lists are no longer individually sortable.
(The same Pr# is used for all favorite lists).
- Samsung J series: deleting channels now physically removes them from
the file. (The TV might automatically append them again when it finds
them in the DVB data stream).
- Samsung J series: editing of channel names is now enabled.
- Samsung J series: favorite E is now also available
