Don't automatically derive BundleFromComponents with Bundle

[alice-i-cecile]

Instead of making BundleFromComponents opt-out, though, would it make sense to have it be opt-in and require #[derive(Bundle, BundleFromComponents)]? That better matches the general convention that a derive only implements a single trait. And if you do need to call take, the trait bound should help guide you to derive the second trait.
