Replaced flames with iceflames in 'You Have 1 Minute' for Bonus Islan…

…d 2.

This addresses bug 949- aparently the OS X implementation of openAL limit the number of sound sources to 64.  Since there were 81 flames in a relatively small area in this area, and each flame has a sound source, this limit was being reached causing a crash.  Replacing each flame with the silent iceflame skirts the issue.

The moral of the story is: FOLLOW LEVEL DESIGN GUIDELINES.
