MediaPlayer: No automatic playlist sorting, sort through right-click drag

Disable automatic sorting of items dragged onto the playlist. Instead,
offer sorting of new items by a submenu from a right-click drag.

MediaPlayer: Add GUI to open network streams

MediaPlayer: Added simple shortcuts to playlist.

Fixes #6562.

Signed-off-by: Augustin Cavalier <waddlesplash@gmail.com>
I tweaked some coding style and added back the missing
B_BACKSPACE shortcut.

* 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.

* Refactor the "Remove and Put into Trash" backend a bit to allow giving it an
index and not work on the current selection only.
* Reenable the code in MainWin that implements the shortcuts to trigger this
feature during playback. Now it uses the Undo/Redo stack and profits from
existing polish.
* Add missing fPlaylist locking in MainWin at several places. Should not have
caused any realworld problems, though.
* Add Undo/Redo shortcuts to MainWin and forward to Playlist window.
* Make sure the Playlist window opens on the same workspace as the player
window. This could be seen when launching MediaPlayer on one workspace, later
moving the window and then opening the Playlist window, it would open on
the original workspace. The new behavior additionally pulls the playlist
when it's already open and you invoke the "Playlist" menu item.
* Added the beginnings of a refactoring to make the Playlist and everything
else use a PlaylistItem class, instead of entry_refs directly. This stuff is
not yet used, though, just compiles.

* I didn't like so much how the "Remove and Move into Trash" feature was
implemented. It didn't reuse existing code and didn't integrate well. No
Undo/Redo except via Tracker, but not in the Playlist... some bugs as well
(Remove had same shortcut as Randomize, Didn't maintain current playback item
if last entry was removed)
* I need to reenable the main window short cut though. This is only temporary.

Adds the option to delete a file from Mediaplayer and move that file to Trash
Works both from main window and PlayList window.
Button that works are B_COMMAND + [delete | d | r] button.
It can be debated what shortcut to use but I needed this function :)
Same goes for the menu i Playlist window. Yell and Ill change :)

What not works are undo and total undo in main window and total undo in Playlist
(total undo = undo files from trash as well as normal undo)

* Added "Randomize" feature to Playlist window (Edit menu). It randomizes
either the selected items, or the entire list if nothing is selected.
* Small cleanups here and there.

* probably fixed the build, did I forget some files before?
* implemented full undo/redo for any playlist operations
