Command to add to queue submissions after bust has begun. about busty

[Cephian]

To do it properly we'd likely have to

1. Update the pinned list messages, including the edge case behavior around if they overflow to the next one. Alternatively we could just send all new messages and unpin the old ones
2. Update the Google form (annoying, maybe impossible if ppl have started voting)
3. Interrupt the main control for loop mid-song playback to add another element (probably not that hard actually)
4. Probably other stuff I have not thought of

It might be nice if this could take the form of a /playlist command, with various subcommands:

• /playlist add - this issue. Takes a file and adds it to the end of the current playlist.
• /playlist remove <index> - removes a song from the current playlist. The index here would start from 1 (so folks could correlate it easily with the pinned message/gform).
• /playlist move <index to move> <index to place song after> - re-order the playlist. For example, playlist move 15 1 would move the song at index 15 to be the second one to play. You'd have to be a bit careful of the edge case of moving while currently busting. For instance, what would happen if you moved the currently playing song?
