A lot would have to change in order to support this. For instance,
variables like `emms-player-playing-p' imply a single player where no
such implication is necessary (no reason for it not to be a list). There
shouldn't be any reason why I can't launch a video with player A (that
can play videos but can't play network streams) and then a soundtrack
for that video with Player B (that can't play videos, but can stream
music).

Stopping the players would default to stopping each in the order of the
last player started, and `emms-stop' could also be called with C-u M-x
emms-stop and take a "playing" player as an interactive argument. These
commands would also gain counterparts with names such as "emms-stop-all"
which would endeavor to stop playback in all of the players currently
running.

Rest assured that the code will live in a separate branch for the near
future (now this branch is local to my machine, and in the future a
branch on the git repo).
