[Open Assets] Hammer Jump for Amy Rose

Not really good at things like this, so I'm gonna keep it simple. I gave Amy a hammer jump using lua.


It can be activated by pressing Spin while running.
If you are underwater, you can press Spin while walking.
(I also removed the ability to press Spin in mid-air to do the aerial attack.)

Update: The hammer jump speed has been lowered to 15 speed. There's now a "Strong Hammer Jump" that activates at full speed.
Update: You can now use the Twinspin ability after performing the Hammer Jump.


Outside of those conditions, you will use the grounded hammer attack as normal.
