- after loading a list it is now ensures that if IsDeleted => OldProgramNr =-1 and for fixing bad files: if OldProgramNr == -1 => IsDeleted = true
- while saving a list, if NewProgramNr == -1, the channel will be set to IsDeleted=true and temporarily gets a sequential NewProgramNr assigned, so that no "-1" or duplicate numbers end up in the file. Afterwards for deleted channels the NewProgramNr will be set back to -1.
- GlobalClone files now set IsDeleted and IsDisabled if a channel was removed
