SpaceBeam : With trails, you can feel projectiles !

Added two different weapons : Bullets and missiles.
Bullets are short-range, high-speed. Missiles are slower, longer range, and can be "controlled" with the ship direction.
Added some particle emitters for thrusters, bullets and missiles, that give a trail feeling.

The video shows a combat between my small ship and 3 generated ennemy ships.
