Mediaplayer: remember position and volume

MediaPlayer: Avoid to recreate the supplier more than needed

* MediaPlayer attempted to recreate each time the media supplier(s),
and implictly it recreated also the BMediaFile. This works fine with
local data that can be accessed fastly, but makes lots of troubles
with network streams such as BMediaIO. The result of this was that
the Streamer plugin has been recreated each time having memory and
network wasted other than performances.
* I tried to keep intact the previous logic, and it looks OK for me,
this has been done by moving out of the Controller the ownership of
the TrackSupplier and adding a little utility class that do the
releasing job previously done by the ObjectDeleter.
* Reviews are appreciated.

* Flesh out attribute support in PlaylistItem/FilePlaylistItem
some more.
* Finish refactoring and abstracting BMediaFile/BMediaTrack
out of the Controller. There is TrackSupplier now and
MediaFileTrackSupplier. One could now implement another
PlaylistItem class besides FilePlaylistItem, which provides
other implementations for TrackSupplier (i.e. for testing
DVD playback).

* Added a temporary solution to add the Audio:Length attribute to audio files,
just like SoundPlay did.

* Changed the PlaylistItem interface to be hopefully more flexible. It can
probably still be improved.
* Renamed EntryRefPlaylistItem to just FilePlaylistItem.
* Moved the "move into Trash" and "restore from Trash" implementation into
FilePlaylistItem. Also added what's needed to allow Tracker to restore the
entry itself.
* Refactored everything to make Playlist use PlaylistItems instead of
entry_refs and all that entails...
* The transition to virtualize PlaylistItems is not complete yet in the
Controller, since it still uses BMediaFile there. But it's much easier to
change that now.
* Objects which keep a PlaylistItem around do correct reference counting, but
some commands could be simplified if they were using references as well. It
still should work correctly, though, if I didn't miss anything. It should also
fix theoretical situations of encountering out-of-memory while messing with
the Playlist leading to inconsistent state between Undo/Redo and then leaking
items because of that.
* Added the discussed change that MediaPlayer checks it's own supported types
before rejecting a file by super type. (untested)
* When importing playlist items, the currently playling item is better
maintained during Undo/Redo.
* Some debugging code added in MediaTrackAudioSupplier, no functional changes.
* Fixed a number of coding style issues and automatic whitespace cleanup.
