Subject: [PATCH] ParseRSS: accept any file with audio/ media type as podcast

There are some podcasts that use audio/opus files (mostly as an alternative,
but still), which makes the audio attachment not being displayed.

Instead of increasing the list of allowed formats (because audio/mp3 would be
quite useful on the list too), I guess it'd be better to give any audio/ media
type to the user-agent and let him worry about it. :^)
