jrobbo grabber: Incorrect channel XMLTV IDs

[max]

I think the jrobbo grabber returns the wrong XMLTV IDs -- specifically, it returns the raw channel names. This flows all the way through Shepherd and causes mythfilldatabase to create new channels with these names in MythTV.

Actually looking more closely I think jrobbo may have changed its channel names from "Channel Ten" to "Ten", "Channel Seven" to "Seven", "ABC " to "ABC", etc. (ABC2 and SBS still worked.) The grabber is hardcoded to translate only particular names so it missed this.

Since jrobbo's source & format can change the grabber probably needs a less strict match.

The matching from the oztivo grabber kept working, so maybe use something like that in jrobbo -- i.e. sort channels names from longest to shortest, and translate to the first match:

# Create a list of channel names from longest to shortest
@clist = sort { length $b <=> length $a } keys %$channels;

sub subme
{
    my $station = shift;

    $station = "SBS NEWS" if ($station eq "SBS-NEWS");

    foreach (@clist)
    {
        return $channels->{$_} if ($station =~ /$_/i);
    }
    print "Warning: station \"$station\" unknown.\n";
    return $station;
}

we'll just have to address this each time it breaks - part of the problem here is that jrobbo's sources keep changing.

committed less specific (and hopefully more robust) channel matching via [391].
