…etradio) (#803)

* [LCD4linux] v5.0-r23 new handling of streams & picons (IPTV or Internetradio)

- new handling of streams & picons (IPTV or Internetradio)
- tiny improvements of code

DESCRIPTION
When a channel (=service reference) with a stream address is selected, the user setting “Show streams '4097; 5001...5003' in **On mode** or in **Media mode** takes effect
or
the user simply leaves this selection to **LCD4linux** (=Autodetect).

**USER setting: GLOBAL -> other**
Show streams '4097; 5001...5003' in mode Auto / On / Media (“Auto”) is default

Note: If “Auto” is set, the system checks which mode Enigma2 is currently in (special thanks to **jbleyel@OpenATV** for the crucial information)

    in TV mode, the stream is then set as IPTV, i.e. display in **On mode**
    in radio mode, the stream is then set as Internet radio, i.e. display in **Media mode** (with cover)
