List channels in logicalChannelNumber order

[3ll3d00d]

Is your feature request related to a problem? Please describe.

Currently the channel list is in some undefined order (not logicalChannelNumber, not lexical channel name, not obviously order they are listed in the json) which makes it quite user unfriendly to use (have to scroll v long list in a dropdown to search for something).

Describe the solution you'd like

1. channels to be listed in logicalChannelNumber order (aka as per the actual channel order when you view the guide)
2. the displayed channel name to be prepended with the logical channel number

Describe alternatives you've considered
customising the media card to enforce a sort order
extending the media card to provide an autocomplete on the source list
