[aur-general] Removal Request

mpd-pulse (http://aur.archlinux.org/packages.php?ID=18722) is deprecated as
mpd in [extra] has pulseaudio support built in. I checked this myself by
following the instructions here:
http://mpd.wikia.com/wiki/PulseAudio#Setting_up_MPD and 'pulse' was indeed
outputted when running 'mpd --version'.
