Bring back the old CyanAlarm alarm tone

For almost two months now I've been wondering why my phone's alarm clock
has lost much of its effectiveness. Today the reason finally hit me: the
CyanAlarm tone had been sneakily replaced in commit ID
dbb169ad!

Although the new tone is certainly more pleasant to listen at and
doesn't cause any heart attacks, it is less effective for heavy
sleepers like myself. This commit brings back the old CyanAlarm
version with the new (tentative) name "Nuclear Launch".
