Scared Stiff (1.5)

use correct/actual S2 sound ROM 1.1 for all game roms >= 1.0, as the publically available set is mislabeled (contains solely 1.0 sound ROMs) to make use of the 'old' S2 1.0 (so what was thought to be 1.1), too, for now use it as additional set with game rom 1.1 thanks mjr for the additional investigation/verification (via the DCS OS version which is greater for the 'new' S2 1.1) [toxieainc]
