Fix for servicetype icons in channelselection screen

    Add detection for streams
    Make it configurable (off, left or right from servicename)
    It can be used/enabled for any skin
    Add the icons. The feature was there for ages but no icons could be
    found thanks for all during discussing/helping to get icons on the
    forum
    I still need to consider how to make the icons better skinable for a
    specific skin
