Casing flight directions

[Keshash]

Changes

Describe adjustments to existing features made in this merge, e.g.

• Thrown casing flecks now align perpendicularly to the gun's aiming angle, instead of always falling to the south side.
• Gun's recoil now increases the speed/distance of casings flying out and decreases the spinning rate. Makes high-caliber, disposable launchers and cannon shells look heavier.

Alternatives

Describe alternative implementations you have considered, e.g.

• Add a modExtension that exposes more fields to xml

Testing

Check tests you have performed:

• Compiles without warnings
• Game runs without errors
• Playtested a colony (specify how long)
