This patch fixes the leak of Objective C objects on start up, which solves the leaking of objects on start up. I also creatied an autorelease pool around the other objective-C calls, more as defensive programming than out of necessity.

The messages no longer appear in the console log when SL starts in 1.20 RC8 (and probably RC7, but I wasn't able to test it before it was pulled)
