Added 'download' icon to playlist and download() function
to player. This is useful for devices that don't have a
browser that can play specific formats. Instead the media
is downloaded. { Note sure if appropriate for livestreams
but I left out the checks anyway }
This adds the 'download' icon for each entry in the playlist.
It is useful for cases where there is no browser support for
a particular media format. Instead it will initiate a direct
access to the URL. { Note: not sure if certain media such
as livestreams should be excluded, but I left them in anyway }
