Give the option of saving the tracks in a new playlist

Is your feature request related to a problem? Please describe.
While sorting without overwriting the tracks in a playlist can take a while, creating a new playlist with the tracks in the desired order is much faster. It's also safer to create a new playlist, as the user will be able to keep the original one.

Describe the solution you'd like
Give the user the option to save his sorted tracks as a new playlist instead of sorting the playlist itself.

Describe alternatives you've considered

• Add a new function to the sorting algorithm file;
• Create a new button on the playlist page or prompt the user whether they want to create a new playlist or edit it.
