Provide some way of using fadestart/fadelen info from those files that
provide it. (Does currently read the info, but it's ignored.)


I wasn't sure whether to add a volume control initially, but having
used it a bit I think I need one. Should probably just use the mixer's
`pcm' setting, adapting code from rexima being the obvious approach.


Really want runtime modification/loading/saving of playlist in at
least the GTK+ version. It's a bit of a pain though, so it might be a
while in coming.


The silent-time-count isn't reset for new tracks. Rarely noticeable,
but if you jump from one currently-silent track to another which
remains silent, it'll skip the new track after less time than usual.


You should be able to specify stopafter time on the cmdline in min:sec
format, since it's displayed that way in the UIs.


The button bitmaps in xaylet are hardcoded to use black. This is bound
to cause problems with dark GTK+ themes. Should see if there's some
way I can get them to use the button-text colour.
