Import local M3U file list as YouTube playlist

Import local M3U playlists into YouTube as playlist.
The script accepts one argument, path to an M3U playlist, such as one produces with:
find mp3/genre/directory -type f > My_genre_name_playlist_name.m3u
It then searches for the best video match to each item in the playlist
and adds it to a newly created PRIVATE YouTube playlist bearing the
M3U playlist file name.
