Treats m3u as pls and attempts to convert it to m3u

[Boris Gjenero]

Trying to play https://lounge-radio.com/ via https://lounge-radio.com/listen128.m3u or http://nl1.streamhosting.ch:80/lounge128.mp3.m3u using Audacious fails. The problem is that, although the playlist is in m3u format, Streamtuner2 treats it as pls and tries to convert it to m3u. The resulting m3u is empty, only containing the #EXTM3U header. Debug output shown when running streamtuner2 -D shows what's going on:

---

Both playlist URLs are served with "Content-Type: audio/x-mpegurl", which seems correct, the URL has the .m3u extension. I see no reason why Streamtuner2 should treat this as a pls.

As a workaround, go to Edit -> Properties -> Options (tab) -> Playlist conversion (section), and enable "Forgo any streaming URL and playlist format and playlist conversion for players".
