THROWING KNIVES

Throwing knives added. Right click to use. If something isn't working let me know and it might be something you have to adjust in the scene (as far as i know, no one has tried pulling a scene yet, so i have no idea if it will work). I assume using git for scenes will work as long as two people dont both modify it and try to merge them. Can pick thrown swords back up for ammo and can end the cutscene with Cutscene.EndScene().
