linkhandler: set title when adding to mpd

You can communicate with MPD using a protocol [1]. A commenter outlined
how to do that in fish [2], this commit adds a POSIX-compliant
implementation to handling of youtube links. In short, when you queue a
youtube link in MPD, it'll now have a title and artist.
