Playlist command

[kthezelais]

I add a playlist command. This feature is used to store tracks into a parallel list of the queue, and this list of tracks can be run on the queue when the user use the command ;;playlist run.

You can find some details on how to use this new command below :

The command ;;playlist Allows you to configure the playlist:

- add <search>: add a title from a search. Then enter the command ;;playlist [1-5] to choose a title from the search list.

- copy: copy the queue into the playlist. If the playlist is not empty, enter the command ;;playlist [1-2] (1: overwrite the playlist, 2: do nothing).

- list: display title's list of the playlist.

- remove <option>: delete one or more titles from the playlist:
     - without option: displays the list of titles in the playlist.
     - all: delete all the titles in the playlist.
     - <number>: delete the title associated with the <number> parameter.

- run <option>: adds all the titles from playlist to the queue.
     - without option: add the titles in order.
     - random: add the titles in the mess.
