Initial re-release

I've cleaned up some of the graphics, got it running with D3D 9 at 60fps now instead of software rendering at 50fps. Modified the bonus rounds to allow you more shurikens on screen, added a help screen to the title, been fixing some annoying bugs.

 
Right now the green knife guys like to glitch out and just stand there, so it's on the todo list. It looks like I already had code in place to make the player bounce when running into an enemy like the arcade game, but I'm sure it was disabled for a reason. It's on the todo list as well, and lots more.
