Description:
When playing a podcast, the "repeat" mode is disabled : once the podcast
has finished playing, you have to double click on it if you want to play
it again, Repeat mode doesn't work.

However, the Repeat button in the toolbar, is not greyed out. To the
user, it looks as if Repeat mode ought to work, but it doesn't as it's a
feature, so it's confusing.

So would be great to make the Repeat button unsensitive/greayed out,
when playing podcasts, to indicate clearly that it's disabled on
purpose.

Also, the "Shuffle" mode (in my use case at least) doesn't make much
sense for podcasts either, so maybe it could be made unsensitive as
well.
