/**********************
The below handles a request for action on the mpd player and/or the return of mpd
player state information.
It is grossly inefficient because everytime there is a request it loads init.php and does a full
instantiation of myMpd. Would be much faster if it only loaded limited info to start, then
just grabbed what it needed. (Prolly tougher to maintain abstraction.)
