Disallow Wimp_SpriteOp 38 (create/remove alpha)

Detail:
  - s/Wimp01 - Add OS_SpriteOp 38 (create/remove alpha) to the list of banned SpriteOp's for Wimp_SpriteOp. OS_SpriteOp 38 is almost always guaranteed to modify the target sprite, and so in keeping with other sprite modification ops it shouldn't be allowed via Wimp_SpriteOp.

  Tested on BB-xM
