New Waepons/Improve the weapon class

[fvultier]

The Weapon class of Orxonox is very limited. The procedure of shooting is always the same: You click a button. Then if you have enough munition a projectile flies away. It would be nice to have weapons that the player/AI can charge up: The longer the shoot button is pressed the more powerful the attack get. Or a weapon that launches a rocket if the player clicks and explodes only if the user clicks a second time.

Steps:

• Understand how the weapon system of orxonox works.

• Implement you new weapon types in C++

• Design a simple weapon that uses the new weapon type

• Change the template of an existing space ship such that it uses your new weapons

• Create a Model and/or a particle effect for the new weapons
