Fixed Dynamite & Elephant & Added Cheat & Secret

Elephants now die properly.
Animals now die from dynamite properly.
Added S A Y E F10 cheat.
Added secret 1/20 chance to make a flying pink elephant with a top hat
above volcano sections.
Made crates despawn from volcano sections. Not sure aout rocks, they
seemed to already despawn. They have been removed again anyway if not.
For some reason I needed to commit again.
