audio/din: Update to 53

Changes since 52:

DIN Is Noise 53:

  /*  new in DIN53:

        launched drones launch drones that launch drones that launch drones....!

          use Drone Params > Defaults > Generations to set the number of \ 
times this can happen

            if Generations = 1,  A drone launcher launches drones (@ a Drones \ 
Per Minute)
            that die at the end of their lifetimes. This is default and the only \ 
behaviour until DIN 52.
            if Generations = 2, A drone launcher launches drones that launch drones.
            if Generations = 3, A drone launcher launches drones that launch \ 
drones that
            launch drones too.
            if Generations = 4, 5, 6, ... this quickly escalates into a \ 
population explosion of drones;
            lots of drones birthing lots of drones, living their life out and \ 
waiting to die can get
            very loud (especially if the Compressor isnt ON), slow down DIN and \ 
maybe even your computer
            beyond rescue. Be careful! :)

            Ways to prevent this population explosion are: keep Generatons low \ 
(Menu > Drone Params
            > Defaults), keep Drones Per Minute (DPM) and Lifetime on the original
            launcher low (Select drone launcher and adjust values from Menu > \ 
Drone Params > Motion) and
            keep the Fall time low (the fade-out time for drone after being \ 
killed, from Menu > Drone
            Params > Defaults)

            The launched drones take the DPM and Lifetime of their parent so \ 
editing carefully the
            parameters of the original launcher is important.

  /*  new default Drones Per Minute (DPM) on a drone launcher (Menu > Drone \ 
Params > Defaults). Assigns a
      DPM when making a drone launcher.  Turn on ~ to assign a DPM at random.

  * re: Auto rotation of drone velocity/acceleration vectors:
      changed Degrees Per Second to Degrees Per Tick

  /* re: Menu > Drone Params > Defaults > Bounces
      when set to 0, launched drones dont bounce off the bottom of the \ 
microtonal keyboard
        but are killed immediately (behaviour until DIN 52)
      when set to -1, drones dont bounce off the bottom of the microtonal \ 
keyboard at all:
        but they are not killed either, they just live their life(time) out

  /* gravity base and tip dont move ie stay fixed as you scroll the microtonal \ 
keyboard in DIN53.
     this is because gravity is now in 'object space' along with the drones and \ 
microtonal ranges.
     until DIN52, gravity was in 'UI space' along with UI controls.

  * repositioned drone arrow UI elements

  ! fixed : DIN not quitting when frozen drones present !
  ! fixed : change size of gravity vector when its modulating !
