  remove fade from the compiz plugin list

Bug description:
  Alt-Tab between applications under Unity requires a fade that takes
  longer than 100 milliseconds, placing the action beyond the response
  limits recommended by the GNOME HIG.

  Since I am capable of alt-tabbing at 5+ keypresses per-second (if the
  LIFO order is predictable - see bug #682973) the fading and alt-tab
  system needs to give a reliable visual response within the window
  between subsequent Alt-tab invocations.

  If the user is working ahead of the display system intermediate
  drawing steps should be dropped and only the cumulative state shown to
  the user.  To reproduce:

    1. Press Alt-tab lots (eg. 20+ times at 5-10 Hz)
    2. Release over the window of your choice

  Expected: that window immediately appears usable within 100 milliseconds
  Actual: Alt-tab pager carries on "catching up" with the user (and since there at multiple windows open this is statistically unlikely to be the window that the user released on).

  The many-many-presses is an extreme example but hopefully clearly
  demonstrates the disconnect between the user's input and the tab
  pager/fade system.
