Enhance playlist and playbakc queue

[m3thm4th]

• Editing big playlists is very daunting at the moment. Moving a track from the bottom to the top of a big playlist takes a lot of time, there is no option for multiple selection and moving/deleting multiple tracks at the same time.

• Long-tap menu shopuld include an option to add that track to another playlist, that menu doesn't appear in the playlist and playlist edit menus.

• Tapping a song in a playlist doesn't open the playback screen

• Any track opened in a playlist becomes the first in the playback queue, if I want to listen the bottom half of a playlist the first half is appended in the queue and there is no way of removing all following tracks except one-by-one. Having multiple selection and "remove all preceding/following tracks" option in the playback queue screen would be very useful.
