- constructor replaces empty masks with full masks (i.e. if no tv/radio/data bit is set, then all bits get set and the list can hold any such channels)
- DataRoot.GetChannelList(SignalSource) works now accordingly to ignore a mask when it is empty in the search criteria (as opposed to the list's SignalSource)
Added checkbox for Data/Other in the reference list dialog
- 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
