Prepend Playlist_index

[Bartholomue]

Would it be possible to add to the options the ability to prepend the playlist index to a file name? I see this is an option with youtube-dl, and it would be great for ordering playlists in the appropriate sequence.

The code that tells ytBATCH where to store and how to name files is always the same for every download and can not be set seperately atm. I will tackle this problem in the near future, this includes redoing some of the core code of ytBATCH.
