Missiles!... (and lot of others things!)

- Modified horizontal sensitivity, to keep the maximum speed unchanged but the acceleration modified, no longer changing the balance of this modifier.
- Corrected dialogues: their size and positions now adapt to the resolution.
- Added the arsenal and artificers.
- The artificers are additional mellings that have a chance to launch missiles, depending on the amount of rubble present in the tank.
- Fixed the shader that had an offset volume texture.
- Improved the ballistics system: shells now have a more varied and controlled movement curve, both for the player cannon and for NPCs.
- Added a colored smoke trail behind the ammunition, allowing you to identify each type of ammunition fired, including those fired by NPCs, and to better visualize their trajectory.
- Added a unit to certain statistics (%, scrap, etc.), for better understanding.
- Adjusted the ballistic characteristics of each ammunition.
