- ChannelList.SignalSource and DataRoot.GetChannelList(SignalSource) are now handled so that if all bits of a given Mask are left 0, the list will accept anything.
i.e. if Tv/Radio/Data is left 0, the list can contain all of them as well as channels that have neither of the 3 bits set.
- added basic unit tests for each loader to ensure test files have the expected numbers of channels in the various sub lists
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
