Update pongo skin

To enable the speed limit in a live voice, you have now four options:
- "Only alert sound"
- "Only audio"
- "Only voice"
- "Voice and alert sound"
audio is automatically taken along the path ux / audio.zip / ui_nextgen / audio / SC1049 from SC1049 folders or another depending on the selected voice, no matter whether TTS or not
