Ninja-san: The animated series

The missing frames don't do this justice, but the following can be seen in this gif:
- Can tell if you're jumping left or right, and flips the sprite accordingly
- Changed the way it pulls out of the leap into the descent so it's time based now.
- Added mid air somersaulting after the initial leap, rotating based on direction of jump.
- Added different sprites and states depending on whether you're above/below/to the side of the collision.

I need to recheck my positioning variables to make sure they sit correctly, but I might wait until after I do proper sprites first and save doing that work twice. Also this is the basic animation system done now, so I've just gotta add proper start and finish states and a timer, and then a basic menu and this prototype is done.
