SCI: Use sound resource priority by default for songs

SCI1 sound resources can have an embedded priority. We now use that by
default, unless an explicit DoSound/SetPriority call overrides it.
Thanks waltervn.

This fixes relative priority of songs in at least PQ3 room 29.

Also increase savegame version to 33.
