Explain the animation "destroy" of destructibles

[Diarandor]

The Lua API does not explain that the animation called "destroy" in the sprite of a destructible is the one used by the engine to show the entity being destroyed. That animation is not even mentioned. Add this!

I think that the "walking" animation is not mentioned either. On the other hand, if it is still planned for Solarus v1.6 to allow lifting all types of entities, the API for destructibles may not be the place to explain these animations.
