[Open Assets] Steven's Amy Abilities 1.4.6

That's it, that's the update. (Though it took me a really long time to figure it out)

to buff the Giant Steps when Amy is Super too.

The Giant Steps will now be doubled in speed when Amy equips the Speed Shoes/Super Sneakers item.

- Giant Steps now use Sonic CD's jump sound.
- The Hammer Jump now has the "Power Spring" sfx overlapped with the normal jump sound.

Removed the jump tapping for the hammer jump, because I figured out that it'd be much better without it.
