Fixed most bugs, so only cosmetic visual things left.

o Support transparency for characters. Needed for cockpit rendering
o Fixed bug in NUT renderer which drawed transparent characters garbled
o Fixed long-standing (and outstanding) bug with SAUD error
o Previous fix fixed music in some cases (scene transitions)
o Fixed bug with palette being reset when smush video is rewind
o Made debug level for insane adjustable at compile time (maybe I will remove it later)
