Support required for radio streaming to Cambridge 851n

[simoncn]

If you disable debug logging and play a radio station using the 851n, you will see this message in the MinimServer log:

HTTPSource: byte-range request could not be satisfied

This means that the 851n is trying to play the radio stream as if it were a disk file by reading portions of the stream instead of reading the stream continuously from start to end. It isn't possible to read portions of a radio stream in this way.

If radio streaming is triggered by the 851n, the 851n knows it is dealing with a radio stream and presumably doesn't attempt to use byte-range requests.
