New rocket launcher and Windows fix

Woot, another build!

I have been implementing a rocket launchers 'class' or file in C that handles the rocket launchers separately. It draws the rocket launchers behind or infront of the player/enemy depending on the direction of the player/enemy. Only implemented on the server side so far.

I've also fixed a major bug for Windows, where the game doesn't start up properly and all you see is the player on a black background. Still getting to the bottom of it but I have a bandaid fix that works for now.

Fwoosh,

Leo.
