- LG GlobalClone: Favorites were not loaded correctly into ChanSort

- LG GlobalClone: some changes that might fix problems where the TV didn't work properly
  with an importet list (ChanSort now modifies less data in the file)
- Menu items for hide/unhide, skip/unskip, lock/unlock are now disabled when these features are not supported by the
  channel list file format
- Applying a .txt reference list (which doesn't contain information about skip/lock/hide) will no longer clear these
  flags in the current channel list
