pitchscreen make it a plugin

full commandline parsing
    -has pitch, speed, time_stretch
 /* pitch_screen
 *  accepts args -q, -g, -p=, -s=, -k=; (= sign is optional)
 * -q silences output splash
 * -g runs the gui (Runs immediately)
 * -p100 would set pitch to 100%
 * -s=90 sets speed to 90% if timestrech is enabled
 * -k=true -k1 enables time stretch -k0 -kf-kn disables
