 * Initializes and runs the game.

 * NOTE
 * If there're no args, the game looks for natives in the folder it is being run in.
 * This doesn't work when running in eclipse, because the game gets run from your workspace
 *  
 * To run the game in eclipse, click the little arrow next to the Run arrow and
 * click "Run configurations..." then go to the "Arguments" tab
 * In "Program arguments:" put "${workspace_loc:spaceout/lib/natives/*YOUROS*}"
 * Then you should be able to run as usual.
