- 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
- 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
