Eliminate duplicate "Cesium" alarm sound

This has been bothering me for some time now.  Figured
it was finally time to squash this bug.

I removed Alarm_Classic.ogg, as the sound thats duplicate
doesnt really have a "classic" sound, and, of course, its
a duplicate.

PS4:  Think I fixed the build error.  Testing again...
