More little red bullets...

Replaced the integers by doubles to improve the aiming and speed accuracy of the bullets.Changed the coloring of the bullets to fade out after time to live expires. Changed the structures a bit to keep the data with the object it belongs to instead of having static variables covering all objects of the same type. The ship has two turrets of which the rate of fire can be controlled by both he analog triggers on the XBOX controller.

(I accidentally.... the previous post. It was about little red bullets obviously)
